GROSS ANATOMY

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: -Vagus nerve (X): A mixed nerve. The sensory fibers of this nerve carry impulses from the pharynx, larynx, and most internal organs to the brain. The motor fibers of this nerve carry impulses to internal organs of the chest and abdomen and to the skeletal muscles of the larynx and pharynx.

Detailed explanation-3: -The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing.

Detailed explanation-4: -vagus nerve, also called X cranial nerve or 10th cranial nerve, longest and most complex of the cranial nerves. The vagus nerve runs from the brain through the face and thorax to the abdomen. It is a mixed nerve that contains parasympathetic fibres.

Detailed explanation-5: -General visceral afferent fibers convey visceral information such as distention of organs and chemical conditions from the blood vessels, heart, lungs, digestive system, and other organ systems and glands into the central nervous system via both spinal and cranial (glossopharyngeal and vagus) nerves.
