TRUE about attachment at ischial tuberosity: (A) Origin of semitendinosus from superolateral area, (B) Origin of semimembranosus from superolateral area, (C) Origin of long head of biceps from inferolateral area, (D) Origin of adductor magnus from inferomedial area
Answer is B. Muscle Origin Semitendinosus Inferomedial impression on upper pa of ischial tuberosity Semimembranosus Superolateral impression on upper pa of ischial tuberosity. Biceps femoris Long head: inferomedial impression on upper pa of ischial tuberositysho head:lateral lip of linea aspera Adductor magnus Lower lateral pa of ischial tuberosity, ramus of ischium, lower pa of inferior ramus of pubis. fig:-ischial tuberosity attachment of muscles
