Which cranial nerve is numbered VII?

• A. Facial nerve (VII)
• B. Trigeminal nerve (V)
• C. Glossopharyngeal nerve (IX)
• D. Vagus nerve (X)

Answer: (A)

Cranial nerves are numbered I through XII in the order they appear along the brainstem. The nerve with the number VII is the facial nerve. It mainly controls the muscles of facial expression and carries taste from the anterior two-thirds of the tongue, plus parasympathetic fibers to lacrimal and salivary glands via branches like the chorda tympani and greater petrosal nerve. This combination of motor facial movement and specific sensory/parasympathetic roles helps distinguish it from the others: the trigeminal nerve (V) handles face sensation and chewing, the glossopharyngeal nerve (IX) serves posterior tongue sensation and throat function, and the vagus nerve (X) provides broad autonomic innervation and throat motor functions.
