Detailed explanation-1: -The vagus nerve, also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that carries sensory fibers that create a pathway that interfaces with the parasympathetic control of the heart, lungs, and digestive tract.

Detailed explanation-2: -The vagus nerve, also known as the vagal nerves, are the main nerves of your parasympathetic nervous system. This system controls specific body functions such as your digestion, heart rate and immune system.

Detailed explanation-3: -The vagus nerve, cranial nerve X, is the major parasympathetic nerve. The nucleus ambiguus and the dorsal motor nuclei in the medulla provide efferent output to the vagus nerve that supplies a variety of internal organs including the heart, lungs, kidney, liver, spleen, pancreas, and the gastrointestinal tract.

Detailed explanation-4: -The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate.

Detailed explanation-5: -The vagus nerve is responsible for the regulation of internal organ functions, such as digestion, heart rate, and respiratory rate, as well as vasomotor activity, and certain reflex actions, such as coughing, sneezing, swallowing, and vomiting (17).
