Final answer:
Cranial Nerve V (trigeminal nerve) has both somatic sensory and somatic motor functions, specifically innervating facial sensations and controlling mastication muscles, respectively. It does not perform special sensory, autonomic sensory, or autonomic motor functions.
Step-by-step explanation:
The Cranial Nerve V, known as the trigeminal nerve, is one of the twelve cranial nerves and performs several essential functions for the human body. When looking at the appropriate functions for CN V, it encompasses both somatic sensory and somatic motor functions.
CN V provides somatic sensory innervation to the face, which includes touch, pain, and temperature sensations. This nerve is also responsible for the somatic motor functions that control the muscles involved in mastication, or chewing. Therefore, the correct functions from the options provided are:
- (a) somatic motor
- (b) somatic sensory
It does not have roles associated with special sensory, autonomic sensory, autonomic motor (parasympathetic), or autonomic motor (sympathetic) functions. These other functions pertain to different cranial nerves and aspects of the nervous system.
