Anatomical Terminology (AT) presents anatomical structures in a unified language for all structures of the human body. However, there are characteristics such as some bone accidents that have not been considered in the TA updates, whether they are eponyms that have not been related to current terms or classically described structures, as is the case of a characteristic bone that is easily observed and palpated in the proximal epiphysis of the tibia, at the level of the lateral condyle, joining the anterolateral tubercle of the tibia with the tuberosity of the tibia. This characteristic corresponds to a linear elevation, described as the insertion site of the iliotibial tract and the tibialis anterior muscle. Based on the above, 65 tibiae from Chilean individuals, adults, of both sexes, 60 belonging to the Universidad de La Frontera and 5 from the Universidad San Sebastián were analyzed, considering as an inclusion criterion the integrity of the compact tissue in the epiphysis proximal. The review of the samples revealed the presence of a linear elevation in 100 % of the cases, joining the tibial tuberosity with the anterolateral tubercle (Gerdy), not observing similar elevation from the tibial tuberosity in the direction of the medial condyle. This elevation is used as a reference for palpation during knee evaluation. Based on the evidence presented, we consider that this elevation should be considered in TA as one more characteristic of the tibia, based on its linear and elevated disposition, in addition to its oblique direction from the tibial tuberosity to the anterolateral tubercle of the tibia, for what we propose to call it the Crista anterolateralis tibiae (anterolateral crest of the tibia).

A successful pregnancy requires a series of interactions, mediated by hormonal, molecular and immunomodulation phenomena. One of these interactions is between the endometrium and the blastocyst, before and during the implantation process. The objective of this literature review is to complement what is described in the classic human embryology literature on endometrial-blastocyst interaction. The bibliographic search was carried out in the MEDLINE database using the terms "implantation", "endometrium" and "embryo", and a manual search was carried out, which included articles from non-indexed journals, textbooks and atlases. Inclusion and exclusion criteria were considered for the selection of articles and other bibliographic resources, including human studies, review and experimentation articles, published in the last 5 years. Articles with animals as experimental subjects, in vitro fertility studies, associated pathologies and articles not related to the subject were excluded. When the selection was completed, the complete texts were examined, in which the exclusion criteria were applied again The search yielded a total of 560 articles, whose analysis of titles and abstracts resulted in 475 excluded works, in relation to different exclusion criteria described above. Therefore, 85 articles were obtained, in which the complete text analysis was performed. From these articles, a total of 34 studies were obtained and the contents selected in this review were: Endometrium, Endometrium trophoblast, Aposition, Adhesion and Migration-Invasion. During the implantation, aninteraction between the endometrium and the trophoblast is generated, with the participation of regulatory molecules of proliferation and differentiation, such as hormonal, molecular and gene expression factors. However, the specific mechanisms of action and interaction must continue to be investigated, to answer questions in the field of human growth and development. [ABSTRACT FROM AUTHOR]
