When the leg extends at the knee, the prime mover is the rectus femoris therefore the antagonist is the _______.
Madhur L.
In the previous questions, we established that the posterior muscles of the knee are flexors of this hinge joint. As you would suspect, the quadriceps femoris will be a prime mover for knee extension/flexion. The distal attachment of the rectus femoris is the base of the patella and indirectly the tibia through the ligament.
