[i] Annotation

Fragments from the book: Ecker A. The anatomy of the frog (1889). The author points out the presence of the ligamentum capitis femoris (LCF) in the frog and the presence of a similar structure in the shoulder joint. The text in Russian is available at the following link: 1889EckerA.

The shoulder-joint. The socket is formed by the posterior border of the scapula, by both the processes of that bone, the outer portion of the coracoid, and besides these by cartilage, which forms the articular surface already described (Fig. 33). In the macerated bone the floor of the socket opens dorsally into a fossa between the processes of the scapula (Fig. 32). This opening, in the natural condition, is closed by synovial membrane only; the cartilage covering the rest of the space being absent (the sac may easily be inflated, either from the joint itself or through the opening). The margin of the socket consists of a labrum, partly fibrous and partly cartilaginous, which is easily removed entire. The capsule, which is attached beneath the caput humeri, arises from this. From the articular cartilage of the ventral margin of the socket, and from the adjacent part of the scapula, proceeds a strong band, which is inserted into the flattened outer surface of the head.

The femur, os femoris (Fig. 44). The shaft is cylindrical, with a slight double or S-shaped curve. In the anterior portion the convexity is directed upwards, in the two hinder thirds downwards. Towards the hinder extremity it is flattened from above downwards. The anterior extremity is a rounded articular head placed directly on the shaft like that of the humerus. This head is somewhat flattened from side to side ; and in structure resembles that of the humerus. The inferior extremity is rounded below, but flattened above (towards the hollow of the knee) and behind.

Hip-joint. The articular cavity is deepened by a fibrous ring, labrum cartilagineum, which fits closely upon the caput femoris ; from this labrum the joint-capsule arises, to be inserted behind the head ; close to the lower border of the cavity a Ligamentum teres arises, which is inserted into the caput femoris.

Who, When, and Where Wrote the Book of Genesis?

  Who, When, and Where Wrote the Book of Genesis?  A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN     CONTENT [i]   Abstract [ii]   Introduction [iii]   Egyptian physician [iv]   Asian diviner [v]   Conclusion [vi]   References [vii]   Application [i]   Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research.

ARTICLE ANNOUNCEMENT: THE BOOK OF BERESHIT AS A GREAT COMPILATION

  Article Announcement: «The Book of Bereshit as a Great Compilation of Texts and Meanings from the Second Intermediate Period of Egypt: A Pilot Culturological, Medical, Archaeological, and Textological Examination of the Legends versus Traditional Attribution»   By Sergey V. Arkhipov, MD, PhD  Joensuu, Finland   Abstract The Book of Bereshit (Genes is) was composed in Egypt during the 17th century BCE and reached its definitive protographic form following the Minoan eruption  of Thera . This study argues that the work was a collaborative effort between an Egyptian physician-encyclopedist and an outstanding scribe of Asiatic origin, operating within a sophisticated administrative and scientific framework. By analyzing anatomical descriptions, Bronze Age economic data, and climatic markers, this paper demonstrates that the text originated as a high-level socio-political commission within the Egyptian House of Life.
