Question

Quizplus · Accepted Answer

The direction of fibers of the medial pterygoid is essentially identical to the direction of fibers of the masseter muscle, which is a large muscle of the jaw that is responsible for closing the jaw and elevating the mandible. The fibers of the temporalis muscle run in a different direction than the fibers of the medial pterygoid, while the fibers of the lateral pterygoid run in a perpendicular direction to the fibers of the medial pterygoid. Therefore, the best choice is B, masseter.
