1802PalmeraniÁ

   Palmerani Á , drawing Jacob wrestling with the angel (1802 ).  Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not prevail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.  ( 1922LeeserI , Genesis (Bereshit) 32:25-26,33) More about the plot in our work:  Ninth month, eleventh day   ( 2024 АрхиповСВ. Девятый месяц, одиннадцатый день ).     Ángel  Palmerani  – Jacob Wrestling with the Angel  ( 1802); original in the  a...

Homo floresiensis

  HOMO FLORESIENSIS Homo floresiensis lived on the island of Flores (Indonesia) 190-50 Kya (2016SutiknaT_RobertsRG). The ancestor of this species is «suspected» to be the Asian subtype Homo erectus, which arrived from the mainland about 800 Kya (2009LyrasGA_DeVosJ). The anatomy of Homo floresiensis is less similar to Homo habilis (2008Gordon_WoodB). Homo floresiensis Author: Cicero Moraes et al.  (Arc-Team)  ; source: wikimedia.org   collection (license CC BY 4.0, no changes). Among the discovered remains of a female Homo floresiensis  ( humanorigins . si . edu )  there is a relatively well-preserved left pelvic bone (LB1/7). It has a « typically human » acetabulum (2009JungersWL_DjubiantonoT:Fig.3). The acetabulum has a complete fusion of the three bones that form it and is not hypoplastic (2012BrownP:Fig.4). The acetabular fossa is rounded and deep, continuing downwards and forwards as a wide acetabular notch. This area is the site of attachment and func...

  Fragments from the book Sandifort E. Descriptio ossium hominis. (1785). The author briefly writes about the attachment of the ligamentum capitis femoris (LCF). Quote p. 104 [Lat] Os ischium… … Qua spectat pelvim (a) os ischion æquabile est, modice cavatum, ab exteriore profunde sinuatum (b). Sinus hic, quem acetabulum vocant, maximus, sere rotundus, est, dividique potest in partes duas, alteram semilunarem quodammodo, cartilagine tectam (c), hinc æquabilem, alteram altius excavatam, asperam (d), glandulæ muciparæ sedem præbentem, & educentem ligamentum teres, quod capiti ossis femoris infigitur (e). … Quote p. 108-109 [Lat] Femoris os … … Caput magnum, globosum, cartilagine lævi incrustatum, oblique positum (b), id est, sursum introrsumque tendens, magnitudine & figura cum acetabulo (i) congruens, intra illud admittitur, illique alligatur per ligamentum teres, quod firmiter adhæret ab altera parte acetabulo, ab altera sinui profundo, inæquabili, qui in dicto capite est (k...

The First Animals

  THE FIRST ANIMALS According to molecular clock data, the separation of the Animal Kingdom from the Plant Kingdom occurred 1609±60 Ma (2004HedgesSB_ShoeJL). Molecular estimates indicate that the last common ancestor of multicellular representatives of the fauna (Metazoa) was Neoproterozoic, most likely younger than 800 million years (2015PisaniD_LiuAG). Biomarkers of metazoan living systems identified in sedimentary deposits indicate their presence in the seas since the Cryogenian period (2018ZumbergeJA_SummonsRE), which began around approximately 720 Ma (2023CohenKM_CarN). Multicellular animals were part of early Ediacaran ecosystems and are found below layers dated to 632.5 ± 0.5 Ma (2007Yin_LHuJ). The oldest fossil of a multicellular organism resembling a sponge (Porifera) is about 600 Ma (2015YinZ_TafforeauP). The last Neoproterozoic glaciation (about 582 Ma) coincides with the appearance of complex organisms in the fossil record (2007BowringSA_AllenPA). Ev...

Human Children. Retelling of Chapter 10

      Short retelling of chapter 10 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 10. THE ARK AND THE CAVE The Book of Genesis does not specify where Noah lived before the flood, but it is plausible his home was in the "land of Nod." To save his family and terrestrial animals, Noah builds an ark measuring "three hundred cubits" long, "fifty cubits" wide, and "thirty cubits" high, coated with pitch inside and out. The vessel has three decks, a pyramidal roof, a side door, and a window, likely at the top. Noah loads his wife, three sons with their wives, and representatives of birds, reptiles, and "clean and unclean cattle." The text lists some "passengers": Noah’s sons, Shem, Ham, and Japheth, and mentions "beasts," "cattle," "creeping things," "flying creatures,"...

1899ParsonsFG

  An excerpt from the article by Parsons FG. The joints of mammals compared with those of man: a course of lectures delivered at the Royal College of Surgeons of England (1899, pp. 301-306). The paper discusses the anatomy and presence of the ligamentum capitis femoris (LCF) in different animals. The author found in an experiment that in kangaroos, the LCF was stretched during hip extension. Below we publish an excerpt from the abstract and a critique of the lecture in the Lancet.   THEJOINTS OF MAMMALS COMPARED WITH THOSE OF MAN: A COUBSE OF LECTURES DELIVERED AT THE ROYAL COLLEGE OF SURGEONS OF ENGLAND.

SOME of the chief points which attract attention in the hip joint of man are the three thickened parts of the capsule called the ilio-femoral, ischio-femoral, and pubo-femoral ligaments, as well as the intra-articular ligamentum teres running from the bottom of the ac...
