Final answer:
Cranial nerve VII is known as the facial nerve, which is responsible for facial expressions, taste, and salivation.
Step-by-step explanation:
The name of cranial nerve VII is the facial nerve. This nerve is responsible for a number of functions including controlling the muscles of facial expression, conveying taste sensations from the anterior two-thirds of the tongue, and providing parasympathetic innervation to lacrimal and salivary glands. Among other cranial nerves, the facial nerve is unique as it contains preganglionic parasympathetic fibers and is critical in functions such as taste and salivation in the anterior oral cavity. The jaw reflex is an example of a reflex tested during the cranial nerve exam which pertains to the trigeminal nerve, primarily a sensory nerve with motor components for mastication.
