What is vagus nerve efferent?

Answer 1

The tenth carotid nerve of human is the vagus nerve.
A cranial nerve that's a major output of the parasympathetic nervous system. The sympathetic system is fright, fight, or flight enhancer, the parasympathetic is the opposite ... sort of relax and digest your last meal. Slows the heart and increases digestion.

Answer 2

The Vagus Nerve is a Cranial Nerve (Number X) that starts in the medulla oblongata of the brainstem and travels downward to various organs of the body. It has been called the "wandering nerve" because of the many areas that it innervates. The Vagus Nerve has two major components, efferent fibers and afferent fibers.

Efferent fibers are those that travel away from the origin of the nerve, the central nervous system (CNS). In this case, Vagus Nerve efferents carry parasympathetic motor control fibers that are associated with the autonomic nervous system (ANS) from the brainstem to organs like the lungs, heart, and those of the gastrointestinal tract. These fibers send signals that assist in the control of those and other organs. These efferent fibers make up about 10% of the Vagus Nerve.

The afferent fibers carry sensory information from the organs back to the brainstem which is part of the central nervous system (CNS).

Answer 3

The vagus nerve innervates from the brain the brain and to much of the body. There is a left and a right vagus nerve. The right vagus nerve (which travels along with the large artery in the neck) primarily controls the heart. The vagus nerves are both afferent and efferent (signals travel from the brain and to the brain). Nerves are classified by man in to fibers, A, B, C. The vagus nerve controls the voice box, your stomach, and innervates with the phrenic nerve, making you hiccough. The Vagus nerve also controls how much acid your stomach secretes, it signals the brain when you are full. It innervates in to other nerves and effects and is affected by other peripheral nervous systems.

Answer 4

The vagus nerve starts in the brain, specifically the medulla. It travels down the neck and "wanders" to the chest and abdomen where it connects to the viscera. It is also called the pneumogastric nerve and the cranial nerve X.

Answer 5

it crosses the internal carotid near the ear and lies in sheath posteriorly in 90% and anteriortly in 2% of patients
