Shingles is caused by reactivation of the varicella-zoster virus, which primarily affects sensory nerves. The trigeminal nerve is responsible for sensation in the mouth, ears, and pharynx, and receives afferent signals from the affected dermatomal region. Choices A, B, and C refer to cervical spinal nerves, which do not innervate the regions affected by shingles in the mouth, ears, and pharynx. Choices E refers to the facial nerve, which is responsible for motor function and sensation in the face but not in the areas affected by shingles in the mouth, ears, and pharynx.
