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...

Article by Walmsley T. A note on the retinacula of Weitbrecht (1916). The author discusses the embryonic development and relationships of the ligamentum capitis femoris (LCF) in humans and animals. A NOTE ON THE RETINACULA OF WEITBRECHT. By THOMAS WALMSLEY, M.B., Senior Demonstrator in Anatomy, University of Glasgow. The synovial membrane of the hip-joint is in extent and attachment similar to that of other diarthroses, but the retinacula of Weitbrecht (or ligaments of Stanley) lend to it a special interest. These retinacula are readily recognized on the interior of the capsule as flattened bands passing inwards towards the margin of the head of the femur from the attachment of the peripheral capsule. The following description of their constitution may be selected as expressive of current opinion. The retinacula are arranged in three groups, superior, middle, and inferior: structurally, they are synovial covered capsular reflections: morphologic...

1861HoldenL

Fragments from the book Holden L. Human Osteology (1861). The author discusses the attachment and anatomy of the ligamentum capitis femoris (LCF) . In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet. Quote pp. 1 66-167 Acetabulum. Lastly, we come to the "acetabulum." This is so named from its resemblance to an ancient vinegar cup. Observe its great depth and hemispherical form adapted for the secure lodgement of the head of the thigh-bone, and for more or less movement in any direction. It looks downwards and outwards so as to transmit the weight of the trunk directly on to the head of the thigh-bone; and the upper or iliac portion of it is by far the thickest and strongest, since it has to support the whole weight of the trunk in the erect posture. All these points are of interest, because they are characteristic of the human skeleton. There are two notches in the margin or "br...

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. [ii] Introduction According to Rabbinic Judais...

Infectious (local process, disease of the whole body) 5. Radiation (X-rays, gamma radiation, particle streams) 6. Medicinal (exposure to medications and their breakdown products) 7.
