1605BauhinC

  Fragment from the book Bauhin C. Theatrum anatomicum (1605). The author writes about the attachment, function, possible elongation and damage of the ligamentum capitis femoris (LCF). Lameness after dislocation is mentioned and its cause is explained. In the margins of the page are references to the works of other authors Vesalius , Laurens , Arch ang ( Archangelo Piccolomini ??? ) . Quote p. 1244. Liber IV. DE LIGAMENTIS OSSIS ILII & sacri et que in toto pede habentur. CAP. XXXIX.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

1734KulmusJA

  Fragments from the book Kulmus JA. Tables anatomiques (1734). The author briefly writes about the anatomy, properties and attachment of the ligamentum capitis femoris (LCF). There are known translations of the treatise into Latin ( 1732KulmusJA ) and German  ( 1740KulmusJA ). Quote p. 56-57 [Fra] 2.) Le Ligament rond quiest court, mais très-fort, tireson origine du fond de: la cavité cotyloïde, aboutit à la fosse qui se trouve à la partie superieure du condyle de l'os de la cuisse. c.

The round ligament is short but very strong; it arises at the bottom of the acetabulum and joins the fossa at the top of the femoral condyle. с . In the upper part of the head there is a recess in which the round ligament is attached. External links Kulmus JA.

386-397John Chrysostom

  Fragment from the book John Chrysostom. Homoliae in Genesim (Homilie on Genesis). The treatise Homiliarum in Genesium, written between about 386 - 397 years in Antioch, now Antakya. J.F. Kelly gives a more precise date – 389 ( fourthcentury.com ). The author mentions ligamentum capitis femoris (LCF) in an animal and an episode of its damage in a human. To denote the LCF, John Chrysostom used the Greek term « νεῦρον ». Translated into Latin, the structure is called «nervum». The Greek text is prepared for machine translation using a service built into the blog from Google or your web browser. See our commentary at the link: 386-397JohnChrysostom [Rus]. Quote [ Grc] ΟΙΜΙΛΙΑ ΝΗ.γ.

1914JonesFW_MorrisH

  We are publishing a chapter from the fifth edition of «Morris's Human Anatomy» (1914). A significant portion of it is dedicated to the ligamentum capitis femoris (LCF). The original text has been edited by Wood Jones. Particularly notable are the illustrations depicting the LCF. Some of them are improved drawings by the first author ( 1879MorrisH ).   Quote pp. 276-284 1. THE HIP-JOINT Class. — Diarthrosis. Subdivision. — Enarthrodia. The hip is the most typical example of a ball-and-socket joint in the body, the round head of the femur being received into the cup-shaped cavity of the acetabulum. Both articular surfaces are coated with cartilage, that covering the head of the femur being thicker above where it has to bear the weight of the body, and thinning out to a mere edge below; the pit for the ligamentum teres is the only part uncoated, but the cartilage is somewhat heaped up around its margin. Covering the acetabulum, the cartilage is horseshoe-shaped, a...

135-170Yehudah ben Ilai

  Sayings of Yehuda ben Ilai extracted from the tractates Pesachim and Chullin (Babylonian Talmud). Babylonian Talmud was written between about 450 - 550 in present-day Iraq (formerly Babylonia). The religious scholar Yehuda ben Ilai points out the distal attachment site of the ligamentum capitis femoris (LCF) and demonstrates knowledge of the possibility of its injury.  See our commentary at the link:   135-170Yehudah ben Ilai [Rus].
