An inability to extend the leg would result from a loss of function of what nerve?
An inability to extend the leg would result from a loss of function of the common peroneal nerve, a branch of the sciatic nerve. This nerve provides motor function to the muscles that extend the leg and dorsiflex the foot. Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.
Is The antagonist muscle to the quadriceps is the hamstring?
The Hamstrings consist of three muscles that have the same action: the Biceps Femoris, Semitendinosus and Semimembranosus. Their actions are to flex the knee joint, adduct the leg, and extend the thigh. The Quadriceps femoris is four muscles of the femur.
