Question

What is the major motor nerve to soft palate?

(a) Trigeminal nerve (CN V)
(b) Facial nerve (CN VII)
(c) Hypoglossal nerve (CN XII)
(d) Vagus nerve (CN X)

Answer 1

The major motor nerve to the soft palate is the Vagus nerve (CN X). The Vagus nerve is responsible for controlling the muscles of the soft palate, as well as the superior pharynx and the gag reflex.

Step-by-step explanation:

The major motor nerve to the soft palate is the Vagus nerve (CN X).

The vagus nerve is responsible for controlling the muscles of the soft palate, as well as the superior pharynx and the gag reflex.

The motor control of the gag reflex is largely controlled by fibers in the vagus nerve, making it the correct answer choice for this question.
