The maned wolf Chrysocyon brachyurus (Illiger, 1815) is the largest canid in South America, weighs about 25 kg as an adult and is threatened of extinction. Anatomical descriptions contribute to the complementation of information on wild species and for conservation, clinical and surgical implications. The purpose of this study was to describe the bones and muscles of the forearm and hand of the maned wolf. The methodology was through the usual dissecting methods in animals preserved in 10% formalin solution. The animals belong to the didactic collection of the Laboratory of Teaching and Research in Wild Animals of the UFU and come from run over. The bones evaluated were: radius, ulna, carpal accessory, carpi ulnar and carpi intermedium; carpal bones I, II, III and IV; metacarpal bones I, II, III, IV, V; proximal phalanges, middle phalanges and distal phalanges from first to fifth finger. The muscles observed were: radial extensor carpal; pronator round; brachioradial; common extensor of fingers; ulnar carpal extensor; lateral extensor of the fingers; supinator; abductor long finger I; flexor carpi radialis; flexor deep fingers; superficial flexor of the fingers; ulnar flexor of the carpus; square pronator; interflexor; lumbrils; short abductor of fingers I and II and short flexor of finger I.

The objective was to describe the anatomical accidents of the long bones of the thoracic limb of Tamandua tetradactyla by means of macroscopic and radiographic analyzes. We used 34 specimens, which were death by running over. Evaluation of the humerus demonstrated the same structures present in domestic animals, besides others without previous description. In the forearm, radius and ulna were completely separated, and although, like the humerus, some of the same anatomical accidents described in other species were identified, we also noticed particularities. All the structures described in the macroscopic analysis were identified on radiography, when performed in at least two orthogonal projections. The anatomic-radiographic structures of the long bones of T. tetradactyla showed great anatomical variation compared to other mammals, which makes the species very unique. Thus knowledge of their particularities is fundamental for safer clinical-surgical approaches. [ABSTRACT FROM AUTHOR]

The species Tapirus terrestris (Linnaeus, 1758) is known as Brazilian tapir is a mammal of the order Perissodactyla, the only order that which occurs endemic in Brazil, considered largest mammal Brazilian. There are few studies related to their morphology. The study aimed to describe the bones and muscles of the thigh T. terrestris. We used four specimens of T. terrestris fixed in 3.7% formaldehyde. For osteological description, the bones were macerated, cleaned and dried, identified and described. For a description of muscle, the muscles were dissected according to the usual techniques in gross anatomy. For the histological description samples were collected every muscle they have been processed and applied stains hematoxylin and eosin, Masson's trichrome, and Orcein Reticulin, followed by analysis by light microscopy. The skeleton of the gluteal region of T.s terrestris consists of hip bone, thigh bone that is formed by the femur. The muscles (M.) that makes up the thigh are M. Tensor fascia lata, M. Biceps femoris, M. Semitendinosus, M. Semimembranosus, M. Gracilis, M. Pectineus, M. Quadriceps femoris, M. Adductor,M. Sartorius and M. quadratus profundus, M. piriformis, M. gemelis e M. obturator internus. Histologically muscles showed striated muscle fibers, collagen fibers, elastic and reticular fibers. We conclude that the T. terrestris have characteristics similar to osteological and muscle of horses, however, some differences were evident fact that can be corroborated by locomotor patterns acquired by the species due to its habitat.
