Detailed explanation-1: -The vagus nerve (cranial nerve [CN] X) is the longest cranial nerve in the body, containing both motor and sensory functions in both the afferent and efferent regards.
Detailed explanation-2: -The vagus nerve is the tenth cranial nerve (CN X) and is the longest mixed cranial nerve. Although we refer to the vagus nerve as singular, it’s actually a pair of nerves that emerge from the left and right side of the medulla oblongata portion of the brain stem.
Detailed explanation-3: -The glossopharyngeal (IX) and vagus (X) nerves mediate the complex interplay between the many functions of the upper aerodigestive tract. Swallowing, breathing, and communicating all rely on delicate interactions between the sensory inputs and motor outputs of many of the cranial nerves.
