Solution
11.rectus femoris is a muscle of anterior compartment of upper leg or thigh.
It is attached to patella.
It help in extension of knee,flexion of thigh and flexion of hip joint.
Synergistic muscle-vastus medialis,vastus intermedius,vastus lateralis( they also cause extension
of kneeand flexion of thigh)
Antagonist muscle-hamstring(flexion of knee)
12.biceps femoris -a muscle of posterior compartment of thigh
It help in flexion of knee by both short and long head of muscle,extension of hip by long head of
muscle and also causes internal and external rotation
Synergistic muscel-semitendinous and semimemranous
Antagonistic muscle- rectus femoris.
