Comments

1886LesshaftP

According to the author, the ligamentum capitis femoris (LCF) reduces shocks and impacts of the articular surfaces. In addition, P. Lesshaft states an anatomical fact: the LCF is located vertically under the part of the acetabulum, which mainly bears the weight of the body. The text is prepared for machine translation using a service built into the blog from Google or your web browser. In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet.

Tiktaalik roseae

TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH). The closest ancestor of Tiktaalik roseae, the fragments of the skeleton of which are relatively well preserved, is Panderichthys.

The shape of the skeleton of the pectoral fin and shoulder girdle suggests that Panderichthys rhombolepis "walked" (2006AhlbergPE_ClackJA). At the very least...

1877MorrisH

An excerpt from the article by Morris H. Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint (1877, pp. 161-170). The author noted that the ligamentum capitis femoris (LCF) is stretched during flexion, adduction, and external rotation. It was found that the LCF is always damaged in hip dislocations, is more often torn from the femur, and is rarely ruptured. Discussion of article see article 1877BrookeC . DISLOCATIONS OF THE THIGH: THEIR MODE OF OCCURRENCE AS INDICATED BY EXPERIMENTS AND THE ANATOMY OF THE HIP-JOINT. BY HENRY MORRIS, M.A., M.B., F.R.C.S., ASSISTANT SURGEON TO, AND LECTURER ON ANATOY1 AT, THE MIDDLESEX HOSPITAL. Received January 9th-Read February 13th, 1877. RECENTLY, whilst making various dissections of the hip-joint, the usually accepted doctrine that dorsal and ischiatic dislocations of the femur occur when the thigh is in a position of adduction appeared to me as very improbable, on anatomi...

Australian Aborigines

AUSTRALIAN ABORIGENES The first cuneiform texts appeared at the dawn of the Sumerian civilization in the period between 3500-3100 BCE. Due to the fact that before this interval there was no writing, an older text mentioning ligamentum capitis femoris (LCF) will never be found. Perhaps a drawing or pictogram of it will be found on a stone. Our assumption is inspired by the study of the rock art of the Australian Aborigines in the style of «X-ray art». Ancient artists, depicting animals and people, often drew bones, internal and external organs, and also designated joints. The minimum age of the early X-ray painting on the western Arnhem Land Escarpment in northern Australia is 5068-6636 years (2017JonesT_WesleyD). Here, in the area of the Burrungui (Nourlangie) and Madjedbebe (Malakunanja II) shelters, rich in rock art, human settlements existed 24-20 Kya (2017MaySK_SanzID). Modern comprehensive analysis indicates the beginning of the settlement of Australia and the territory near...

280-352Rava

Sayings of Rava extracted from the tractates Chullin and Horayot (Babylonian Talmud). Babylonian Talmud was written between about 450 - 550 in present-day Iraq (formerly Babylonia). The rabbi identifies the location and distal attachment site of the ligamentum capitis femoris (LCF) and demonstrates knowledge of its function. See our commentary at the link: 280-352Rava [Rus]. Quote 1. [Heb] Chullin 54b3 (original source: sefaria.org ) Quote 2. [Heb] Chullin 91a12 (original source: sefaria.org ) Quote 3. [Heb] Horayot 12a:16 (original source: sefaria.org ) Translation Quote 1. [Eng] Chullin 54b3 The Gemara addresses the matter itself: Rav Mattana says: This head of the femur that was completely dislocated renders the animal a tereifa. And Rava said: The animal is kosher, but if its sinew holding the bone in place is cut, it is a tereifa. The Gemara concludes: And the halakha is: Even if the sinew is cut, the animal is still kosher...

1851HyrtlJ

The author expresses a classic view on the functions of the ligamentum capitis femoris (LCF): a conductor of blood vessels and a limiter of adduction of the femur. J. Hyrtl believed that it was impossible to completely dislocate the hip without tearing the LCF. Hyrtl J. Lehrbuch der Anatomie des Menschen, mit Rücksicht auf physiologische Begründung und praktische Anwendung. Wien: W. Braumüller, 1851. [fragment] Quote p. 265 In der Höhle des Gelenks liegt das runde Band des Schenkelkopfes (Lig. teres), welches an der Incisura acetabuli entspringt, und bei richtiger Neigung des Beckens, senkrecht zur Grube des Schenkelkopfes aufsteigt. Es beschränkt dieses Band die Zuziehung des Schenkels, und schreibt zugleich den durch die Incisura acetabuli eindringenden Blutgefässen den Weg vor, den sie zum Oberschenkelkopfe zu nehmen haben. Da das Band, wenn es in die Höhle des Gelenkes vorragen würde, durch Reibung viel zu leiden hätte, so...

THE TRUTH INJECTION

The "Truth Injection" Impact on AI and 4 Billion People: Informed Insight or AI Hallucination? Sergey V. Arkhipov & Google Gemini CONTENT [i] Abstract [ii] A Briefe Backstory [iii] Interview [iv] References [v] Application [i] Abstract While examining modern biblical criticism, I engaged in a discussion with Artificial Intelligence regarding my book, “ 50 Tables of Evidence for the Composition of Genesis in Late Second Intermediate Period Egypt ” . The machine’s apocalyptic prediction concerning half of the world's population and the evolution of computer technology left me puzzled. To verify this prophecy and seek counsel from "natural intelligence," I am publishing my conversation with the AI. This may be of interest to others, as will response to the machine’s final last question regarding religious worldview: «Now that the "antidote" is in your system, do you feel more prepared to face a world without a "sacred" fou...
