1883SuttonJB

  According to the author, the ligamentum capitis femoris (LCF) is a tendon of the pectineus muscle, separated from it in consequence of skeletal modifications.   THE LIGAMENTUM TERES By J. B. SUTTON, Demonstrator of Anatomy, Middlesex Hospital. (PLATE VIII.) The round ligament of the coxo-femoral articulation has long been an anatomical puzzle, consequently many diverse notions exist concerning it. Some anatomists ascribe to this hollow band of fibrous tissue very important functions in the mechanism of the hip-joint; others deprive it of all glory, simply assigning to it the menial duty of conveying blood-vessels to the head of the femur. Certain authors content themselves with a brief description of its attachments; others give elaborate and detailed accounts, extending over several pages, of its anatomy and supposed function. My object in the present communication is to show that this singular ligament is nothing more than the tendon of the pectineus muscle, sepa...

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...

1883MorelC_DuvalM

  Fragments from the book Morel C, Duval M. Manuel de l'anatomiste: anatomie descriptive et dissection. Asselin (1883). The selected passages on the ligamentum capitis femoris (LCF) and its function. The authors saw that in an upright position, the LCF is vertical, taut, and apparently serves to support the weight of the body on the head of the femur, especially due to the two anterior and posterior parts, which are quite strong. 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. Quote p. 117 L'extrémité supérieure du fémur (fig. 64) est formée par une tête arrondie (1) que supporte un col (2) inséré obliquement sur le corps, avec tubérosités développées au niveau de cette insertion. La tête, très régulièrement arrondie, formant plus de la moitié d'une sphère, est tourn...
