Detailed explanation-1: -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-2: -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-3: -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-4: -The vagus nerve plays an important role in maintaining physiological homeostasis, which includes reflex pathways that regulate cardiac function. The link between vagus nerve activity and the high-frequency component of heart rate variability (HRV) has been well established, correlating with vagal tone.
