Immersive virtual reality (i‐VR) is a powerful tool that can be used to explore virtual models in three dimensions. It could therefore be a valuable tool to supplement anatomical teaching by providing opportunities to explore spatial anatomical relationships in a virtual environment. However, there is a lack of consensus in the literature as to its effectiveness as a teaching modality when compared to the use of cadaveric material. The aim of our study was to compare the effectiveness of i‐VR in facilitating understanding of different anatomical regions when compared with cadaveric prosections for a cohort of first‐ and second‐year undergraduate medical students. Students (n = 92) enrolled in the MBBS program at Queen Mary University of London undertook an assessment, answering questions using either Oculus i‐VR headsets, the Human Anatomy VR™ application, or prosection materials. Utilizing ANOVA with Sidak's multiple comparison test, we found no significant difference between prosections and i‐VR scores in the abdomen (p = 0.6745), upper limb (p = 0.8557), or lower limb groups (p = 0.9973), suggesting that i‐VR may be a viable alternative to prosections in these regions. However, students scored significantly higher when using prosections when compared to i‐VR for the thoracic region (p < 0.0001). This may be due to a greater need for visuospatial understanding of 3D relationships when viewing anatomical cavities, which is challenged by a virtual environment. Our study supports the use of i‐VR in anatomical teaching but highlights that there is significant variation in the efficacy of this tool for the study of different anatomical regions.

Purpose. This research aims to assess the diversification of pedagogical and learning methodologies, leveraging advanced technological tools within a dental hygiene educational framework. Methods. Students enrolled in the dental hygiene program were considered as population sample, divided in two groups: The test group (N=16) subjected to the investigation of the virtual dissection table (VDT) and the control group (n=17) who attended lectures using traditional teaching method. The control group’s performance was assessed through a 40-item multiple-choice questionnaire and an open-ended question; the test group was evaluated via a final test consisting of a presentation on an anatomical topic and a 40-item multiple-choice questionnaire. The final grade derived from the mean score of the final tests, and it was assigned on a scale of 30/30. Additionally, the test group’s perceptions toward the use of the VDT were gauged through an evaluative questionnaire comprising 7 questions. Results. The study found a statistically significant difference in failure rates between the control group and the test group. However, the average exam scores did not show a statistically significant difference between the two groups, despite the test group showing some improvement. The evaluation survey results indicated high levels of satisfaction with the use of the VDT, with the quality of the virtual images, anatomical resources, and the user-friendly interface. Additionally, students strongly supported integrating traditional lectures with VDT laboratory sessions, with no negative feedback reported. Conclusions. The VDT represents an innovative anatomy teaching tool, warmly welcomed by healthcare profession students, whose performances were positively affected. [ABSTRACT FROM AUTHOR]

Regional anatomy is an important component of surgical and clinical practice because it helps clinicians envisage the specifics of the structures relevant to the case at hand. This study was designed to evaluate some clinically important indices which could aid regional anesthesia of the head in the Nigerian indigenous pig (NIP). Twenty-four (10 males and 14 females) skulls of adult NIP were examined to record 10 parameters. Data obtained were statistically analysed using the Student's t-test and Pearson Correlation, with significance set at p<0.05. The study revealed that 50% of the indices were higher in female skulls but were not statistically significant. The mandibular length was, however, significantly longer in male skulls (19.0 ± 0.41), compared to females (18.0 ± 0.26). The distance from the facial crest to the infraorbital foramen was 1.3 ± 0.10 cm and 1.5 ± 0.08 cm, while that from the supraorbital foramen to the nasal bone was 2.1 ± 0.06 cm and 1.9 ± 0.06 cm, in male and female skulls, respectively. Pearson correlation analysis revealed a positive relationship between the distance from the facial crest to infraorbital foramen and that from infraorbital foramen to medial canthus of the orbit (r=.669). An accessory supraorbital foramen was seen in 12 (50%) of all the 24 skulls, just as several lateral mental foramina were observed on the rostro-lateral surface of the mandibular rami. Data generated provide clinically important information on the skull of adult Nigerian indigenous pigs which can be used as landmarks for tracking and desensitizing the branches of the frontal nerve (supraorbital), the maxillary nerve (Infraorbital) and the mandibular nerve, during the regional anaesthesia of the head, for tooth extraction procedures and the treatment of injuries and fractures. These results may also be useful for comparative anatomical, developmental, forensic, and clinical studies. [ABSTRACT FROM AUTHOR]

Anatomy is an important component in the vertical integration of basic science and clinical practice. Two common pedagogies are cadaveric dissection and examination of prosected specimens. Comparative studies mostly evaluate their immediate effectiveness. A randomized controlled trial design was employed to compare both the immediate and long‐term effectiveness of dissection and prosection. Eighty third‐year medical students undergoing their surgical rotation from the Yong Loo Lin School of Medicine were randomized into two groups: dissection and prosection. Each participated in a one‐day hands‐on course following a similar outline that demonstrated surgical anatomy in the context of its clinical relevance. A pre‐course test was conducted to establish baseline knowledge. A post‐course test was conducted immediately after and at a one‐year interval to evaluate learner outcome and knowledge retention. A post‐course survey was conducted to assess participant perception. Thirty‐nine and thirty‐eight participants for the dissection and prosection groups, respectively, were included for analysis. There was no significant difference between mean pre‐course test scores between the dissection and prosection groups [12.6 (3.47) vs. 12.7 (3.16), P > 0.05]. Both the mean immediate [27.9 (4.30) vs. 24.9 (4.25), P < 0.05] and 1 year [23.9 (4.15) vs. 19.9 (4.05), P < 0.05] post‐course test scores were significantly higher in the dissection group. However, when adjusted for course duration [dissection group took longer than prosection group (mean 411 vs. 265 min)], these findings were negated. There is no conclusive evidence of either pedagogy being superior in teaching surgical anatomy. Based on learner surveys, dissection provides a greater learner experience. [ABSTRACT FROM AUTHOR]

Important anatomical structures such as mandibular incisive canal, tongue foramen, and mouth floor vessels may be damaged during implant surgery in the mandibular anterior region, which may lead to mouth floor hematoma, asphyxia, pain, paresthesia and other symptoms. In severe cases, this can be life-threatening. The insufficient alveolar bone space and the anatomical variation of blood vessels and nerves in the mandibular anterior region increase the risk of blood vessel and nerve injury during implant surgery. In case of vascular injury, airway control and hemostasis should be performed, and in case of nerve injury, implant removal and early medical treatment should be performed. To avoid vascular and nerve injury during implant surgery in the mandibular anterior region, it is necessary to be familiar with the anatomical structure, take cone-beam computed tomography, design properly before surgery, and use digital technology during surgery to achieve accurate implant placement. This article summarizes the anatomical structure of the mandibular anterior region, discusses the prevention strategies of vascular and nerve injuries in this region, and discusses the treatment methods after the occurrence of vascular and nerve injuries, to provide clinical reference.

The canalis sinuosus, a canal containing the anterior superior alveolar nerve bundle, originates from the infraorbital canal and extends along the maxillary sinus and nasal cavity edges to the anterior maxilla. It was once regarded as an anatomical variation. However, with the widespread application of cone beam computed tomography (CBCT), the detection rate of canalis sinuosus in the population has increased. The canalis sinuosus exhibits diverse courses, branching into multiple accessory canals and terminating at the nasal floor or the anterior tooth region, with the majority traversing the palatal side of the central incisor. The anterior superior alveolar nerve bundle within the canalis sinuosus not only innervates and nourishes the maxillary anterior teeth and the corresponding soft tissues, and the maxillary sinus mucosa, but also relates to the nasal septum, lateral nasal wall, and parts of the palatal mucosa. To minimize surgical complications, strategies for preventing and treating canalis sinuosus injuries need to be investigated. Preoperatively, CBCT is used to identify the canalis sinuosus and to virtually design implant placement at a distance of more than 2 mm from the canalis sinuosus. Intraoperatively, assessing bleeding and patient comfort, complemented by precision surgical techniques such as the use of implant surgical guide plates. Postoperatively, CBCT is used to examine the relationship between the implant and the canalis sinuosus, and treatment of canalis sinuosus injuries can be tailored based on the patient's symptoms. This review summarizes the detection of canalis sinuosus in the population, its anatomical characteristics, and the physiological functions in the anterior maxilla, and discusses strategies for avoiding canalis sinuosus injuries during implant surgery, thereby enhancing clinical awareness and providing references for clinical decision-making.

Objective: To investigate the morphological characteristics of the glenohumeral joint (including the glenoid and coracoid) in the Chinese population and determine the feasibility of designing coracoid osteotomy based on the preoperative glenoid defect arc length by constructing glenoid defect models and simulating suture button fixation Latarjet procedure., Methods: Twelve shoulder joint specimens from 6 adult cadavers donated voluntarily were harvested. First, whether the coracoacromial ligament and conjoint tendon connected was anatomically observed and their intersection point was identified. The vertical distance from the intersection point to the coracoid, the maximum allowable osteotomy length starting from the intersection point, and the maximum osteotomy angle were measured. Next, the anteroinferior glenoid defect models of different degrees were randomly constructed. The arc length and area of the glenoid defect were measured. Based on the arc length of the glenoid defect of the model, the size of coracoid oblique osteotomy was designed and the actual length and angle of the coracoid osteotomy were measured. A limited osteotomy suture button fixation Latarjet procedure with the coracoacromial ligament and pectoralis minor preservation was performed and the position of coracoid block was observed., Results: All shoulder joint specimens exhibited crossing fibers between the coracoacromial ligament and the conjoint tendon. The vertical distance from the tip of the coracoid to the coracoid return point was 24.8-32.2 mm (mean, 28.5 mm). The maximum allowable osteotomy length starting from the intersection point was 26.7-36.9 mm (mean, 32.0 mm). The maximum osteotomy angle was 58.8°-71.9° (mean, 63.5°). Based on the anteroinferior glenoid defect model, the arc length of the glenoid defect was 22.6-29.4 mm (mean, 26.0 mm); the ratio of glenoid defect was 20.8%-26.2% (mean, 23.7%). Based on the coracoid block, the length of the coracoid osteotomy was 23.5-31.4 mm (mean, 26.4 mm); the osteotomy angle was 51.3°-69.2° (mean, 57.1°). There was no significant difference between the arc length of the glenoid defect and the length of the coracoid osteotomy ( P> 0.05). After simulating the suture button fixation Latarjet procedure, the highest points of the coracoid block (suture loop fixation position) in all models located below the optimal center point, with the bone block concentrated in the anteroinferior glenoid defect position., Conclusion: The size of the coracoid is generally sufficient to meet the needs of repairing larger glenoid defects. The oblique osteotomy with preserving the coracoacromial ligament may potentially replace the traditional Latarjet osteotomy method.

The modiolus of the face manifests the interesting landmark for facial muscles attachment. The strong connective tissue fibres play an important role in the clinical setting, especially in the aesthetic and dental surgeries. In the fourth week of intrauterine life, the development of the modiolus evolves in accordance with the growth of muscles of facial expression. Microscopically, a white, tendinous structure with the thick irregular collagenous connective tissue of collagen fibres predominance appeared to be the modiolus. Modiolus is morphologically a fibromuscular muscle situated on the lateral border of the mouth. The formation of the nasolabial fold is important and a well-developed modiolus provide a toned face. Several works of literature forementioned the number of facial muscles attached to the modiolus but no definitive similarity are identified. This review summarizes the updated morphological features and applied anatomy of the facial modiolus with its muscle attachment. [ABSTRACT FROM AUTHOR]

Anatomical examinations have been designed to assess topographical and/or applied knowledge of anatomy with or without the inclusion of visual resources such as cadaveric specimens or images, radiological images, and/or clinical photographs. Multimedia learning theories have advanced the understanding of how words and images are processed during learning. However, the evidence of the impact of including anatomical and radiological images within written assessments is sparse. This study investigates the impact of including images within clinically oriented single‐best‐answer questions on students' scores in a tailored online tool. Second‐year medical students (n = 174) from six schools in the United Kingdom participated voluntarily in the examination, and 55 students provided free‐text comments which were thematically analyzed. All questions were categorized as to whether their stimulus format was purely textual or included an associated image. The type (anatomical and radiological image) and deep structure of images (question referring to a bone or soft tissue on the image) were taken into consideration. Students scored significantly better on questions with images compared to questions without images (P < 0.001), and on questions referring to bones than to soft tissue (P < 0.001), but no difference was found in their performance on anatomical and radiological image questions. The coding highlighted areas of "test applicability" and "challenges faced by the students." In conclusion, images are critical in medical practice for investigating a patient's anatomy, and this study sets out a way to understand the effects of images on students' performance and their views in commonly employed written assessments.

The Saanen goat is known as the greatest milk producer among small ruminat breeds. However, its morphometric features still remain unclear. Therefore, the present work aimed to investigate the functional anatomy of the upper and lower jaws as well as the volumetric properties of the male and female Saanen goat for clinical applications. The heads of 20 adult animals (10 males and 10 females) were included. Totally, 22 morphometric parameters were measured on three dimensional computed tomographic images using RadiAnt DICOM Viewer software and some parameters were measured on hot macerated sample. The mean volume of paranasal sinuses as well as conchal sinuses were estimated using stereological method. Based on the results, the differences between males and females were not significant (p>0.05) in all desired parameters. The frontal and lacrimal sinuses were the largest and smallest paranasal sinus in both sexes. Also, the dorsal and middle conchal sinuses were the largest and smallest ones, respectively. The common nasal meatus was the smallest and ventral meatus was the largest meatus in the nasal cavity. In conclusion, these findings provide a basic data that would be useful in blocking terminal branches of the cranial nerves in this breed for surgical purpose or teeth injuries treatment.

Background: The superficial palmar arch is a crucial blood supply to the palm. However, it exhibits significant variations, posing challenges in surgical procedures. Gaining a comprehensive understanding of the relationship between different types, physiological indices, and the clinical significance of the superficial palmar arch will enhance the accuracy of diagnosing and treating patients., Materials and Methods: In this study, we dissected a total of 72 specimens, comprising 39 males and 33 females. We observed the type, length, and diameter of the superficial palmar arch and analyzed its correlation with the disease. Additionally, we conducted Doppler ultrasound measurements on 20 healthy volunteers (10 males and 10 females) and 18 patients with superficial palmar arch injury (10 males and 8 females) to assess the classification, diameter, intimal thickness, and blood flow velocity of the superficial palmar arch. We collected information on 9 male patients with finger fracture and observed the classification of the superficial palmar arch, fracture healing time, and basic function recovery time. Lastly, we analyzed rare variant specimens encountered during the anatomy process., Results: In the exploration of human anatomy, there were four types of superficial palmar arch: ulnar artery arch type in 17 cases (23.61%), radial ulnar artery type in 46 cases (63.89%), ulnar artery without arch type in 6 cases (8.33%), and 3 cases (4.17%) of double arch type of radial and ulnar artery. One case non-arched type was found in imaging examination (5%). In one elderly male specimen, the hand's superficial palmar arch artery was tortuous and dilated. In addition, there was a positive correlation between the diameter and length of the superficial palmar arch (except the second common palmar digital artery in women), among which the ulnar artery and the third common palmar digital artery had the strongest correlation. Compared to healthy volunteers, patients with ulnar injury in the Radial-ulnar artery type exhibited a decrease in the diameter and blood flow velocity of the ulnar artery, as well as the second and third common palmar digital arteries. No such change was observed in patients with radial injury. Additionally, patients with ulnar injury in other types of Radial-ulnar artery also experienced a decrease in the diameter and blood flow velocity of the ulnar artery. Finger fracture patients with Ulnar artery with arch and Ulnar artery without arch had shorter fracture healing time and basic function recovery time compared to those with Radial-ulnar artery type., Conclusions: This study investigated the relationship between the classification, physiological index, and clinical significance of the superficial palmar arch at all levels. The results demonstrated that when the superficial palmar arch is damaged, it is important to consider both the classification and the site of damage, as this can potentially result in improved therapeutic outcomes. These findings provide a basis for future clinical research.

Objective To explore the surgical efficacy and to measure the displacement distance of different points on SMAS in the simulation of facial SMAS separation and tightening. Methods Ten adult fresh cadaverous head specimens (20 sides) were selected. Surgical instruments were used to simulate the SMAS separation and tightening to perform extensive subcutaneous dissection. The dissection range was from medial side to nasolabial groove, inferomedial side to labiomandibular groove, downward to 5.0 cm under the earlobe and then backward extended to the hairline. The SMAS layer was cut vertically in front of the tragus, and the SMAS was cut at the position of 0.5 cm under the zygomatic arch which parallel to the zygomatic arch. The maximum range of vertical and horizontal separation was 7.0 cm × 6.0 cm. Nine points were selected on the SMAS. In the condition of SMAS layer was intact, the maximum force of 50 N was used to pull upward and outward along the horizontal and vertical direction of zygomatic arch. The data of horizontal and vertical position change of 9 points were recorded separately. Each data was measured 3 times and the average was taken. The pulling force and angle required for the maximum displacement of each point in the horizontal and vertical direction was calculated by the trigonometric function method. Results (1) The larger the range of SMAS separation, the stronger the effect on point A, B and C and the farther the displacement. The fixation structures such as isolated zygomatic ligament and and buccal ligament were beneficial to the enhancement of SMAS. (2) The displacement distance of points at different locations of SMAS was different. The distance of horizontal movement was irregular. (3) The points on SMAS closer to the ear, the farther the displacement distance in the vertical direction, that is A''＞A'＞A, B''＞B'＞B and C''＞C'＞C. (4) The points on SMAS closer to the foot, the farther the displacement distance in the vertical direction, that is A＞B＞C, A'＞B'＞C' and A''＞B''＞C''. The average pulling angle of ABC line was 30°C, A'B'C' line was 51°Cand A''B''C'' line was 70°C. Conclusion The fascia structure of SMAS in each region of cheek is different and the displacement of each part after pulling force is different. The larger the fascia separation range of SMAS, the better the lifting efficacy. The maximum displacement in vertical and horizontal direction of different points require different angles of pulling force. [ABSTRACT FROM AUTHOR]

Objective: To improve the clinical utility of the plantaris tendon mainly by summarizing its anatomical characteristics, biomechanical properties, harvesting methods, and its applications in ligament reconstruction., Methods: The relevant literature from domestic and international databases regarding the anatomical and biomechanical characteristics of the plantaris tendon and its applications in ligament reconstruction was comprehensively reviewed and systematically summarized., Results: The plantaris tendons have an absence. The majority of plantaris tendon forms a fan-shape on the anterior and medial sides of the Achilles tendon and terminates at the calcaneal tuberosity. There are significant differences in biomechanical parameters between plantaris tendon with different numbers of strands, and multi strand plantaris tendon have significant advantages over single strand tendon. The plantaris tendon can be harvested through proximal and distal approaches, and it is necessary to ensure that there are no obvious anatomical variations or adhesions in the surrounding area before harvesting. The plantaris tendon is commonly utilized in ligament reconstruction around the ankle joint or suture reinforcement for Achilles tendon rupture, with satisfactory effectiveness. There is limited research on the use of plantar tendon in the reconstruction of upper limb and knee joint ligaments., Conclusion: The plantaris tendon is relatively superficial, easy to be harvested, and has less impact on local function. The plantaris tendon is commonly utilized in ligaments reconstruction around the ankle joint or suture reinforcement for Achilles tendon rupture. The study on the plantaris tendon for upper limbs and knee joints ligament reconstruction is rarely and require further research.

While case‐based discussions can empower students to apply knowledge to contextual clinical situations, scheduling these activities is a challenge in crowded curricula. Case‐based eLearning activities, derived from existing cases discussed within anatomy small group tutorials, were created incorporating principles such as interactivity, reinforcement, and feedback. Over half of the students accessed one or more of these online cases, with 18% accessing all eight online cases provided. Access increased as the semester progressed, particularly just before summative examinations, implying students used these primarily as revision aides. Students rated both formats highly, but favored the online format with regard to enjoyment (P = 0.048), learning (P = 0.101), and feedback (P = 0.086). However, more students discussed these cases in small group tutorials within the anatomy dissecting room than completed them online (122 vs. 67) and themes emerging from free text comments included a desire to have more time dedicated to these cases during small group tutorials, and an appreciation for the opportunity for discussion with staff and learning through doing. Additionally, native English speakers rated the anatomy room discussions significantly higher in all aspects than non‐native English speakers, suggesting that non‐native speakers may be hesitant or reluctant to fully participate in front of peers. While online case‐based learning activities are a useful adjunct to anatomy teaching, particularly for revision, assumptions that "digital natives" have an innate preference for digital resources require critical evaluation, as students still place a high value on opportunities for discussion with staff during their studies.

Shoulder dystocia is a clear example that allows us to approach applied anatomy. The importance of anatomical knowledge for the correct resolution of a case of shoulder dystocia is well known and accepted. In these cases this basic knowledge of anatomy allows us to: * Recognize the maternal and fetal structures that will cause the problem. * Understand the interaction between both these structures at the time of labor and the dynamic changes that may occur as a result of it. * Provide the surgical basis for their potential resolution through specific maneuvers. * Understand how maternal and especially fetal complications arise due to inadequate execution of these maneuvers. The purpose of this study is to assess the retention of anatomical knowledge by comparing a group of medical students, recent medical graduates, and health professionals related to delivery care, based on learning based on the problem of shoulder dystocia. This study involved three cohorts: A) 16 second-year students of Medicine. B) 17 recent graduates. C) 16 trained professionals. The individuals of the 3 cohorts were evaluated by means of a questionnaire that included 15 multiple choice questions, designed to identify anatomical elements related to the pelvis and perineum, pelvimetry, fetal anatomy of the calvaria [calotte] and the fontanels, brachial plexus and bones and joints of the shoulder girdle and elbow. The data were analyzed individually and by groups, so that no participant could be identified. The difference between the correct responses of group A with those of group B, the difference between those of group B with those of group C, and finally those of group A with those of group C. When comparing the results of the different groups, the fall in the general retention (difference between A and C) was very important, in 56.25%. This makes retention of knowledge a matter of concern. [ABSTRACT FROM AUTHOR]

Objective: To conduct anatomical study on the iliac crest chimeric tissue flap and summarize its effectiveness of clinical application in repairing limb wounds., Methods: Latex perfusion and anatomical study were performed on 6 fresh adult cadaver specimens with 12 sides, to observe the initial location, distribution, quantity, and direction of the common circumflexa iliac artery, the deep circumflexa iliac artery, and the superficial circumflexa iliac artery, and to measure their initial external diameter. Between December 2020 and September 2022, the iliac crest chimeric tissue flap repair was performed on 5 patients with soft tissue of limbs and bone defects. There were 3 males and 2 females, with an average age of 46 years (range, 23-60 years). Among them, there were 3 cases of radii and skin soft tissue defects and 2 cases of tibia and skin soft tissue defects. The length of bone defects was 4-8 cm and the area of skin soft tissue defects ranged from 9 cm×5 cm to 15 cm×6 cm. The length of the iliac flap was 4-8 cm and the area of skin flap ranged from 12.0 cm×5.5 cm to 16.0 cm×8.0 cm. The donor sites were directly sutured., Results: Anatomical studies showed that there were 10 common circumflex iliac arteries in 5 specimens, which originated from the lateral or posterolateral side of the transition between the external iliac artery and the femoral artery, with a length of 1.2-1.6 cm and an initial external diameter of 0.8-1.4 mm. In 1 specimen without common circumflexa iliac artery, the superficial and deep circumflex iliac arteries originated from the external iliac artery and the femoral artery, respectively, while the rest originated from the common circumflex iliac artery. The length of superficial circumflex iliac artery was 4.6-6.7 cm, and the initial external diameter was 0.4-0.8 mm. There were 3-6 perforator vessels along the way. The length of deep circumflex iliac artery was 7.8-9.2 cm, and the initial external diameter was 0.5-0.7 mm. There were 3-5 muscular branches, 4-6 periosteal branches, and 2-3 musculocutaneous branches along the way. Based on the anatomical observation results, all iliac crest chimeric tissue flaps were successfully resected and survived after operation. The wounds at recipient and donor sites healed by first intention. All patients were followed up 8-24 months, with an average of 12 months. The tissue flap has good appearance and soft texture. X-ray film reexamination showed that all the osteotomy healed, and no obvious bone resorption was observed during follow-up., Conclusion: The common circumflex iliac artery, deep circumflex iliac artery, and superficial circumflex iliac artery were anatomically constant, and it was safe and reliable to use iliac crest chimeric tissue flap in repairing the soft tissue and bone defects of limbs.

Medical schools have traditionally used a lecture and dissection-based approach for educating students about human anatomy. There is growing interest in the adoption of alternative teaching and learning activities (TLAs) that incorporate the use of cadaveric prosection and computer-based learning into musculoskeletal (MSK) anatomy curricula. The purpose of this investigation was to examine retrospectively how different TLAs influenced student perceptions about learning, and performance on MSK anatomy examinations. Pre-clerkship students from the same medical school were compared. One group completed 15 hours of dissection-based laboratory instruction; another group completed 15 hours of prosection-based laboratory instruction. All other aspects of the curricula were the same. Information was gathered about student perceptions using a standardized survey that compared six different TLAs on eight specific learning objectives. Academic performance on examinations was compared. Ninety-three medical students (50% of first year class/34% of second year class) participated. Only 27 had taken a MSK anatomy course prior to enrolling in medicine. Both groups rated learning via medical imaging and clinical case-based scenarios highly. While each group also ranked both methods of cadaveric teaching highly, only the prosection group thought there was a significant difference. No differences in academic performance were noted between groups. Data support the inclusion of cadaveric-based teaching, medical imaging and clinical case-based scenarios as key elements of a MSK anatomy curriculum, and suggest that academic performance is not influenced by the method of cadaveric instruction. These results should help guide the selection of effective MSK anatomy TLAs within undergraduate medical programs. [ABSTRACT FROM AUTHOR]

This article initiates a theoretical reflection about the importance of bringing health as a horizon in the teaching of Applied Anatomy and the potential of art as an instrument to do so. First, we look into the concept of health, using it to frame the process of learning about bodies in secondary schools. Second, we present a case study represented by a course in Applied Anatomy that illustrates how health appears directly connected to learning dynamics, in which art is used to foster students' subjective engagement, facilitating the appropriation of what is learnt in class, and its use in their everyday life. Finally, we discuss the connections between art and anatomy, illustrating them with extracts from students' reflections. This case study supports the explicit inclusion of health in the educational frame of Applied Anatomy, proposing it as an empowering strategy to foster self-care and healthy habits in high school students.
