Hip Anatomy and Ontogeny of Lower Limb Musculature in Three Species of Nonhuman Primates
Gross organization of the hip musculature in Microcebus murinus, lateral view of left hind limb. (a)–(d) show a single adult specimen at various stages of dissection. (a) The thigh musculature is intact, showing the large vastus lateralis (VL) balanced by a large biceps femoris (BF). These muscles partially obscure the posterior portion of gluteal musculature (G). (b) BF removed, exposing the caudofemoralis (Cf) and femorcoccygeus (Fc). (c) When the Fc is removed, additional musculature remains (*), running parallel, but deep to the Fc. (d) This muscle is shown with its sacral point of origin removed; the Fc has been removed to better emphasize *; a different adult is shown in (e)–(f) with the BF removed (e), and VL resected (f). (g) A third adult is shown, in an advance stage of dissection, emphasizing *, which may be an accessory head of the Fc. Sm, semimembranosus; St, semitendinosus.
