Answer to Question 1

ANS: A
The signs and symptoms of temporomandibular joint syndrome range from mild aching to severe, sharp pain in and around the TMJs. Typically, there is pain with movement of the joint, particularly with chewing. There is tenderness of the masticatory muscles. The pain is often referred to the ear, causing pain, tinnitus, and hearing difficulties. Stress can cause jaw clenching or bruxism, resulting in fatigue or spasm of the masticatory muscles and, in turn, TMJ pain.

Answer to Question 2

ANS: C
Cranial nerve VII, the facial nerve, controls facial expressions or motor function of the facial muscles. The disorder that causes unilateral facial muscle dysfunction and inability to close the eye is Bell's palsy. Cranial nerve V, the trigeminal nerve, controls the sensation of the face and function of the masseter muscle. Cranial nerve III, the oculomotor nerve, controls the pupil and movement of eyes. Cranial nerve X is the vagus nerve, which is demonstrated by testing the gag reflex.
