Final answer:
The facial nerve (CN VII) contains both motor and sensory fibers, playing a role in facial muscle movement, taste sensation, and parasympathetic control of glands.
Step-by-step explanation:
The facial nerve (CN VII) is a type of cranial nerve that falls into the category of both motor and sensory nerves. This nerve has a significant role in facial expressions, as it controls the muscles of the face for movement. Additionally, it has sensory functions related to taste sensations, and it also contains preganglionic parasympathetic fibers that are involved in the control of the salivary and lacrimal glands. A commonly used mnemonic to remember the functions of cranial nerves is, "Some Say Marry Money But My Brother Says Brains Beauty Matter More," which highlights the basic function of each nerve, indicating that the facial nerve is both sensory and motor.
