THIGH MUSCLES: POSTERIOR COMPARTMENT

     The posterior compartment of the thigh in humans contains the hamstrings: the semimembranosus, semitendinosus, and biceps femoris.  These muscles extend the thigh and flex the knee.

The biceps femoris seems to have originated as two separate muscles.  One of these two originated on the vertebral column and remnants of this part of the muscle are occasionally observed in primates.
