Question

which muscle and nerve pair is responsible for knee flexion from the following choices? peroneals, superficial peroneal tibialis anterior, deep peroneal quadriceps, femoral hamstring, sciatic

Explanation:

• Peroneals and the Superficial Peroneal nerve control ankle eversion, not knee flexion.
• Tibialis Anterior and the Deep Peroneal nerve control ankle dorsiflexion, not knee flexion.
• Quadriceps and the Femoral nerve are responsible for knee extension, the opposite of flexion.
• The Hamstring muscles (biceps femoris, semitendinosus, semimembranosus) are the primary knee flexors, and they are innervated by the Sciatic nerve.

Answer:

Hamstring, Sciatic
