- 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.

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.).he right nerve branches from the vagus at the root of the neck around the right subclavian artery. It courses superiorly in the tracheoesophageal groove to enter the larynx between the cricopharyngeus and the esophagus.

Vagus nerve stimulation Vagus nerve stimulation. Overview. Vagus nerve stimulation is a procedure that involves implantation of a device that stimulates the vagus nerve with electrical impulses. There's one vagus nerve on each side of your body, running from your brainstem through your neck to your chest and abdomen.

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.lectrical stimulation of the vagus nerve, called vagus nerve stimulation (VNS), is sometimes used to treat people with epilepsy or depression.

- An altitude passes through a vertex and is at right-angles to the opposite side. The diagram shows all three altitudes which are concurrent at a point called the orthocentre. Triangle showing three perpindicular bisectors. A perpendicular bisector passes through the midpoint of a side and at right-angles to that side. The diagram shows all three perpendicular bisectors which are concurrent at a point called the circumcentre (the centre of the surrounding circle). Make sure you know the difference between these types of line. It's easy to get them confused, so take the time to learn their names and properties.

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).

The Vagus Nerve (CN X) There are s omatic and visceral components to the sensory function of the vagus nerve. Somatic refers to sensation from the skin and muscles. This is provided by the auricular nerve, which innervates the skin of the posterior part of the external auditory canal and external ear.he vagus nerve is the 10 th cranial nerve (CN X). It is a functionally diverse nerve, offering many different modalities of innervation.

Vagus Nerve and Vagus Nerve Disorder The vagus nerve is actually two cranial nerves that extend from the brain stem and connect down to the viscera. Sometimes this nerve is referred to as cranial nerve X, the 10 th cranial nerve or the wandering nerve.These 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.hese nerves are used to send a variety of signals throughout the body, but will also transfer signals back to the brain.

Vagus nerve stimulation The vagus nerve is one of the cranial nerves, meaning a nerve that is connected directly to the brain. Output nerve fibres control muscles responsible for swallowing, coughing and voice sounds. Input nerve fibres transmit sensations and electrical feedback from the heart, lung, stomach and upper bowel to the brain.bout 80% of the nerve fibres in the left vagus nerve are input fibres transmitting, from the body to the brain, and the output fibres have minimal heart connections, making the left vagus nerve a suitable wire into the brain.

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.

What is the function of the 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.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.The vagus nerve comprises of two sensory ganglia which are segmented into superior and inferior vagal ganglia.agus 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 Stimulator (VNS) Implantation for Children A Vagus Nerve Stimulator (VNS) is a device used to treat seizures when seizure drugs are not effective and surgery is not possible. VNS consists of a pacemaker-like generator that is implanted in the chest wall and is programmed by the physician to stimulate the vagus nerve in the neck. Thin wires are threaded under the skin and woven around the vagus nerve in the neck.

Vagus Nerve Disorders The vagus nerve is actually two nerves, both of which run from the brain stem and branch out separately, down the body, across the abdomen and to the main organs such as the heart and stomach.he vagus nerve is directly responsible for a number of bodily functions, such as breathing, maintaining digestive function, keeping the brain up to date with what we have eaten and/or digested and monitoring the heart beat to keep it regular.
