Origin.—Long head on the tuber of theischium, short head the linea aspera(lateral Hp). Insertion.—^Thehead of the fibula. The semitendinosus and thesemimembranosus also arise onthe tuber of the ischium, and areinserted on the tibia, medial surf aceand back of head.

Thebiceps tendon may be felt behindthe lateral epicondyle; the twoothers, behind the medial epicondyle, making the borders of adeep space—the popliteal space, or ham. They are called ham-string tendons. MUSCLES OF THE LOWER EXTREMITY. 107 Fascial insertion ofgluteus maximus Biceps Vastus lateralis Plan tans Gastrocnemius Solcus Peroneus longus
