Which of the Following Structures Listed Below is Innervated by the Vagus

Question

Which of the following structures listed below is innervated by the vagus nerve?
A)Parotid salivary gland
B)Floor of the mouth
C)Sternocleidomastoid muscle
D)Soft palate muscles

Accepted Answer

The soft palate muscles are innervated by the vagus nerve, specifically the pharyngeal branch of the vagus nerve (cranial nerve X). The parotid salivary gland is actually innervated by the glossopharyngeal nerve (cranial nerve IX), the floor of the mouth is innervated by the hypoglossal nerve (cranial nerve XII), and the sternocleidomastoid muscle is innervated by the accessory nerve (cranial nerve XI).
