1845HollsteinL

  Fragments from the book Hollstein L. Compendium der Anatomie des Menschen (1865). The author discusses the anatomy of the ligamentum capitis femoris (LCF), and mentions its synonyms. The text is prepared for machine translation using a service built into the blog from Google or your web browser.   Quote p. 144 Das Lig am. teres s. rotundum femoris (Fig. 50, 7.) hat eine dreieckige Gestalt, und ist mit seiner Basis in dem Fundus acetabuli, mit seiner rundlichen Spitze in der Fovea capitis ossis femoris befestigt. Es besteht aus einem Bündel Sehnenfasern, und erhält von der Synovialmembran einen scheidenformigen Ueberzug; bisweilen existirt letzterer allein, und manchmal felilt das Band ganz und gar. Fig. 50. Seitliche Ansicht der Bänder des Beckens und Hüftgelenks.   Quote p. 145 Die weite Synovialmembran überzieht den Schenkelkopf, geht alsdann als Scheide des Ligam. teres zur Gelenkpfanne über, welche sie ebenfalls auskleidet, und schlägt sich hierauf über die ...

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 ).
