Vagus nerve The vagus nerve is one of 12 cranial nerves. It is the longest of the cranial nerves, extending from the brainstem to the abdomen by way of multiple organs including the heart, esophagus, and lungs.his is an overreaction of the body to certain stimuli, like the sight of blood, which involves the stimulation of the vagus nerve. This stimulation causes a drop in blood pressure and heart rate. Less blood flows to brain, resulting in loss of consciousness.

Vagus Nerve Stimulation Vagus nerve stimulation (VNS Therapy®) is designed to prevent seizures by sending regular, mild pulses of electrical energy to the brain via the vagus nerve. These pulses are supplied by a device something like a pacemaker. 1  The VNS device is sometimes referred to as a pacemaker for the brain..  The vagus nerve is part of the autonomic nervous system, which controls functions of the body that are not under voluntary control, such as the heart rate.

The Vagus Nerve (CN X) The vagus nerve is the 10 th cranial nerve (CN X). It is a functionally diverse nerve, offering many different modalities of innervation. Due to its widespread functions, pathology of the vagus nerve is implicated in a vast variety of clinical cases. In this article we shall look at its anatomical course, motor, sensory and autonomic functions.

What is the function of the Vagus nerve? It gets this name because the nerve wanders from the brain stem via various organs in the neck, thorax and abdomen. The vagus nerve is two nerves that go through the brain stem and enter different parts of the body such as the heart and the stomach.Vagus nerve leaves the brain stem from the rootlets present in the medulla that has been found to be caudal to the rootlets in the ninth carnial nerve.t gets this name because the nerve wanders from the brain stem via various organs in the neck, thorax and abdomen.

Vagus Nerve Vagotomy is a procedure wherein a branch of the vagus nerve is cut. Usually, the nerves of Latarjet which supply the stomach are cut to treat gastric ulcer. Vagus nerve facilitates peristalsis of the gastrointestinal tract.Secretion of gastric acid is relevant in the process.et us trace where the vagus nerve starts and ends. 1  It all starts from the medulla. 2  The rootlets go the the jugular foramen. 3  Inside this hole are the jugular and nodose sensory ganglia. 4  The one that passes through the lateral side of the skull is the auricular branch.

Cranial Nerves - Anatomy & Physiology The vagus nerve is part of the group of cranial nerves responsible for innervation of structures derived from the branchial arches. It is also part of a group together with the glossopharyngeal and accessory nerves that passes through the jugular foramen which is termed the vagus group.ranial nerves are those nerves which arise from the brain and brain stem rather than the spinal cord. Nerves arising from the spinal cord are the peripheral nerves. There are 12 pairs of cranial nerves and these pairs of nerves passage through foramina in the skull, either individually or in groups.

Vagus Nerve and Vagus Nerve Disorder The vagus nerve runs throughout the body and is responsible for the function and regulation of several bodily systems such as the heart and digestive tracts. The vagus nerve is one of the largest nerve systems in the body.The name vagus is Latin for wandering, which describes the long and complicated path this nerve takes through the body and all of the different systems it comes in contact with.agus nerve disorders are basically broken down into two categories. There are the disorders that are caused by a nerve that is underactive or not functioning properly and there are those that are caused by your vagus nerve overacting to the stimuli it receives. Overactive vagus nerves can cause frequent fainting.

Vagus Nerve Anatomy The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibers, as well as general and special visceral efferent fibers. (See Table 1, below.).

The Importance of the Vagus Nerve The vagus nerve helps control several muscles of the throat and of the voicebox. It also supplies the heart, lungs, major blood vessels of the chest, and the gastrointestinal tract. The vagus nerve has a major role in regulating the heart rate, and keeping the gastrointestinal tract in working order.

Introduction to the Vagus Nerve The vagus nerve is the paired tenth cranial nerve that branches out from the brain and supplies parts of the gastrointestinal system such as the stomach, and parts of the respiratory system such as the lungs. To supply vital organs, it has further to travel than the other cranial nerves.

Vagus nerve The vagus is also called the pneumogastric nerve since it innervates both the lungs and the stomach. The vagus runs posterior to the common carotid artery and internal jugular vein inside the carotid sheath. Both right and left vagus nerves descend from the brain in the carotid sheath, lateral to the carotid artery.
