Quizplus · Accepted Answer

The gastrocnemius and hamstrings are responsible for flexion of the leg at the knee joint. If these muscles were paralyzed, the person would be unable to execute this action. The gluteal muscles are primarily responsible for extension and rotation of the hip joint, and the peroneus and soleus are involved in movements of the foot and ankle, respectively.
