Australopithecus afarensis

AUSTRALOPITHECUS AFARENSIS In 1735, Carl Linnaeus (1707-1778) placed humans as a species «Homo nosce te ipsum» in the order Anthropomorpha along with monkeys and sloths (1735LinneC). In a publication in 1758, the naturalist transferred humans to the order Primates (1758LinneC). Today, humans and chimpanzees are united in the tribe Hominini, as descended from a common ancestor (2001GrovesCP). It has been established that the chromosome that distinguishes humans from monkeys was formed before 4.5 Ma (2022PoszewieckaB_GambinA). The hominin subfamily Sahelanthropus tchadensis lived in the Republic of Chad (Central Africa) from 7.2±0.31 to 6.8±0.45 Ma (2008LebatardAE_BrunetM; 2012ReynoldsSC_GallagherA). Reconstruction of its musculoskeletal system showed that the creature could have been an upright bipedal primate (2005ZollikoferCP_BrunetM). Fossils of what is probably the first bipedal representative of the hominid family Orrorin tugenensis, lived 6.1-5.7 Ma and still retained adapta...

1879TillauxPJ

The author discusses the anatomy, topography, and role of the ligamentum capitis femoris (LCF). According to P.J. Tillaux, this structure "...is the retaining ligament; it prevents the head from being pressed in the upper part against the bottom of the acetabulum." Similar views were expressed earlier by 1820PallettaGB , 1857TurnerW , and 1874SavoryWS . The author does not deny that the LCF also serves as a conduit for vessels and nerves, supporting M.P.C.Sappey . At the same time, the priority of this view should be recognized for 1820PallettaGB .

Human Children. Retelling of Chapter 8

Short retelling of chapter 1 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 8. THE LAND OF NOD Cain’s family settled in the land of "Nod," where they established a "city." We propose this tribal group followed a route later known as the Great Khorasan Road, leading Cain, son of Adam, to the Kermanshah Valley in the central Zagros Mountains. There, we believe he founded the settlement of "Enoch," its remnants linked to the archaeological site of Sheikh-e Abad (34°36'42"N, 47°16'11"E). In this village, the newcomers mastered musical instruments, developed metalworking techniques, and some adopted nomadic herding, living in "tents with flocks." As a farmer, Cain likely preserved knowledge of agriculture. Favorable conditions, division of labor, and acquired skills probably fueled population growth among thes...

1687BlancardS

Fragment from the book Blancard S. Anatomia reformata (1687). The author writes about the attachment and function of the ligamentum capitis femoris (LCF). Quote p. 263 [Lat] Appendices habet superius inferiusque insignes, processibus suisjunctas. Supcrior appendix cum adjuncto processus, amplum, globosumque femoris caput constituit, valida cervice subnixum, quod intra cavitatem ossis ischii, ilium, & pubis concursi productam, (acetabulum alias, pyxidemque) reconditur. Detinctur in hoc sinu robustis ligamentis: lato uno, & membranoso, quod articulum totum circumdat, tum rotundo altero, & tereti, quod ab ipsa cavitate productum, statim in caput susceptum demittitur. Translation [Eng] Above and below, there are remarkable appendages connected with processes. The upper appendage together with the process attached to it forms a large and round head of the femur, supported by a strong neck, which is placed inside the cavity formed by the fusion of bones: ischium, ilium and ...

BIOMECHANICS OF THE HIP JOINT WITHOUT LCF

Biomechanics of the hip joint without LCF Do you remember the comparison of the ligamentum teres with the spring element of a cart? ( 1874SavoryWS ). An analogy could arise after reading the book Bell J. The Principles of Surgery (1801) . Most orthopedists still think so.
