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.

Vagus Nerve The Latin “vag” means “vagrant” or “wandering.” Knowing its distribution throughout the body, it is fit to call the vagus (pronunciation: VAY-gus) nerve as such [ 1, 2 ]. Unlike the other cranial nerves, vagus nerve is spread in different organs, making its functions much more appreciated.

Vagus Nerve Anatomy Gross 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.).ibers from the dorsal motor nucleus X pass through the spinal trigeminal nucleus and tract, emerging from the medulla oblongata lateral surface to join the rest of the vagus. Visceral sensory (afferent general and special visceral). Nerve cells are located in the inferior (nodose) ganglion of the vagus.

What is the function of the Vagus nerve? Vagus Nerve is one such cranial nerve that also happens to be the longest nerves in the body that innervates the throat, thorax, abdominal muscles and other organs and has several functions, which is why it is one of the most important parts of our nervous system.he 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.

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.hese nerves are used to send a variety of signals throughout the body, but will also transfer signals back to the brain. The vagus nerve is also known for wandering through the body, weaving through the abdomen and branching into other nerves that extend through the limbs and organs.

Function of the Vagus Nerve The vagus nerve is known as the wandering nerve because it has multiple branches that diverge from two thick stems rooted in the cerebellum and brainstem that wander to the lowest viscera of our abdomen touching our hearts and most major organs along the way. Vagus means wandering in Latin.

cranial nerve A cranial nerve is a nerve that emerges directly from the brain of vertebrates, as distinct from a spinal nerve, which emerges from the spinal cord. All the cranial nerves, except the vagus nerve, pass through the foramina of the skull to innervate structures in the head, neck, and facial region. The cranial nerves are part of the peripheral nervous system (as distinct from the central nervous system, which consists of the brain and spinal cord).

- What is Vagus Nerve? It is known to be one of the longest of all the cranial nerves. The name Vagus Nerve, has originated from the Latin word, which means ‘wandering’. It gets this name because the nerve wanders from the brain stem via various organs in the neck, thorax and abdomen.

- It involves implanting a pacemaker-like device that generates pulses of electricity to stimulate the vagus nerve. The vagus nerve is one of the 12 cranial nerves, which conduct impulses between the brain and other parts of the brain and va rious body structures, mostly in the head and neck. The vagus nerve-the longest of the cranial nerves-also extends to organs in the chest and abdomen. (The word vagus comes from a Latin word for wandering.') It serves many organs and structures, including the larynx (voice box), lungs, heart and gastrointestinal tract.

- Some of the main functions of the Vagus Nerve include, 1  Breathing. 2  Speech. 3  Sweating. Helping in keeping the larynx open during breathing.  Monitoring and regulating the 1  heartbeat. Informing the brain of the food that is ingested and food that has been digested.  The Vagus Nerve performs the major function of emptying the gastric region of food.

Vagus nerve Electrical stimulation of the vagus nerve, called vagus nerve stimulation (VNS), is sometimes used to treat people with epilepsy or depression.The vagus nerve is involved in one of the most common causes of fainting, called vasovagal syncope.This 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.lectrical stimulation of the vagus nerve, called vagus nerve stimulation (VNS), is sometimes used to treat people with epilepsy or depression.

Function of the Vagus Nerve The vagus nerve is used to regulate the heartbeat and the muscle movement necessary to keep you breathing. This nerve also regulates the chemical levels in the digestive system so that the intestines can process food and keep track of what types of nutrients are being gained from the food that is taken in.nly the spinal column is bigger. Sometimes this nerve is referred to as cranial nerve X, the 10th cranial nerve. The vagus is used to send a variety of signals throughout the body, but will also transfer signals back to the brain.

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.

Vagus nerve stimulation Vagus nerve stimulation or vagal nerve stimulation is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an adjunctive treatment for certain types of intractable epilepsy and treatment-resistant depression.

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.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.

Vagus Nerve Stimulation The vagus nerve is one of 12 pairs of cranial nerves that originate in the brain and is part of the autonomic nervous system, which controls involuntary body functions.The nerve passes through the neck as it travels between the chest and abdomen and the lower part of the brain.agus nerve stimulation (VNS) sends regular, mild pulses of electrical energy to the brain via the vagus nerve, through a device that is similar to a pacemaker. There is no physical involvement of the brain in this surgery and patients cannot generally feel the pulses.

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.
