A Correct answer
Explanation

The infratemporal fossa contains two of the four principle muscles of mastication, medial and lateral pterygoid. The tendon of a third muscle, temporalis, is also found in this region. The remaining muscle, masseter, lies on the lateral surface of the ramus, but is considered here with the muscles of mastication. The masticatory muscles are most immediately concerned with movements to the mandible at the temporomandibular joints.
