Sciatic nerve It is the longest and widest single nerve in the human body, going from the top of the leg to the foot on the posterior aspect. The sciatic nerve provides the connection to the nervous system for nearly the whole of the skin of the leg, the muscles of the back of the thigh, and those of the leg and foot.It is derived from spinal nerves L4 to S3.he sciatic nerve provides the connection to the nervous system for nearly the whole of the skin of the leg, the muscles of the back of the thigh, and those of the leg and foot.

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.

Vagus Nerve Stimulation 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.

What is sixth nerve palsy? Sixth nerve palsy results from dysfunction or damage of your sixth cranial nerve, also known as the abducens nerve. This causes problems with eye movement. The sixth cranial nerve sends signals to your lateral rectus muscle.This is a small muscle that attaches to the outer side of your eye.ixth nerve palsy may affect one or both eyes, depending on its cause. The most common symptom of sixth nerve palsy is double vision when both eyes are open. This is more common when looking far away or when looking in the direction of the affected eye.

- 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.

Sixth nerve palsy From Wikipedia, the free encyclopedia. Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye.ecause the nerve emerges near the bottom of the brain, it is often the first nerve compressed when there is any rise in intracranial pressure. Different presentations of the condition, or associations with other conditions, can help to localize the site of the lesion along the VIth cranial nerve pathway.

- Sixth nerve palsy is a disorder affecting the sixth nerve, which supplies the lateral rectus muscle. This ocular muscle is responsible for turning the eyeball outward, away from the nose. When a person has sixth nerve palsy, the eye begins to point inward toward the nose, often resulting in double vision. Sixth nerve palsy is sometimes known as abducens nerve palsy or cranial nerve VI palsy.

Top 30 Doctor insights on: Vagus Nerve Tachycardia 1st, take your pulse: The vagus nerve is a nerve that goes directly from the brain to various organs to run normal activities like regulation of the gut activity, heart rate and gland secretion. Irritation of the nerve often causes a decline in pulse rate (and lower blood pressure, dizziness and /or fainting).

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.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.

Sciatic nerve The sciatic nerve is the dominant nerve that innervates the lower back and the lower extremities. It travels from the lower spine, through the pelvis, and down each leg. It is the longest and widest nerve in the human body. The sciatic nerve primarily supplies the muscles of the lower leg, including the calf, ankle, and the back portion of the knee. It also supplies sensation to the sole of the foot, the ankle, the entire lower leg, and the back of the thigh. The sciatic nerve branches into different parts of the body along its path, hence its ability to supply such a large area of the body.

What does the Vagus Nerve Do? Vagus nerve is among the 12 cranial nerves that exit the skull instead of exiting through vertebral column or spine. It’s the tenth of the cranial nerves. Nerves are very intricate and they supply important motor and sensory information to the brain neurons in order to allow for critical activities.

What You Need to Know About the Vagus Nerve SHARES. The vagus is one of the larger more important nerves in the human body. One key role that it plays is as the “reset” button to counteract when our alarm system has been set off resulting in the infamous fight, flight or freeze response as some type of threat has been perceived.lso note that the vagus nerve is the “vagabond” nerve that wanders around and surrounds our heart and core area. It is heart-centered and noted as the nerve of intuition and the nerve of compassion. When we feel safe, without threat or anxiety, these abilities and inclinations are free to expand.

Vital Vagus: What is the Vagus Nerve and What Does it Do? Olga Kabel. The vagus nerve can be thought of as a superhighway that connects your body and your brain. It innervates most organs in the body; the messages zip along its five lanes of traffic with four lanes delivering information from the body to the brain and one lane moving information from the brain to the body.

What does the parasympathetic nervous system do? A Dr. William Salt, MD, Gastroenterology, answered. The parasympathetic branch of the autonomic nervous system (ANS) has nerve fibers that originate in the cranial (top) and sacral (bottom) segments of the spinal cord. The parasympathetic branch calms the body, which is the precise opposite of the sympathetic branch.

FAQâs The longest cranial nerve in the body, the vagus nerve regulates both the heart and the digestion. Although spoken of as if it is one nerve, the vagus nerve includes both a right and left vagus nerve. It regulates the parasympathetic nervous system, the calming, relaxing system of the body. Proper vagus nerve function influences the following: 1) Digestion: The vagus nerve innervates digestive organs involved in everything from swallowing to intestinal motility.

Initiating the Response Sensory nerve cells pass the perception of a threat, or stress, from the environment to the hypothalamus in the brain. Neurosecretory cells in the hypothalamus transmit a signal to the pituitary gland inciting cells there to release a chemical messenger into the bloodstream. Simultaneously, the hypothalamus transmits a nerve signal down the spinal cord. Both the chemical messenger and nerve impulse will travel to the same destination, the adrenal gland.

What is the function of trochlear nerve? Without the use of the nerve, the superior oblique eye muscle will no longer function properly. The muscle, not the trochlear nerve, is what physically moves the eyeball. Double vision, otherwise known as diplopia, results from problems with either the muscle or the nerve.t serves the superior oblique eye muscle and connects to the annular tendon. As a result, it processes brain signals to move the eyes up and down, and also outwards. Whether due to a head injury or a complication of surgery, damage to this nerve will compromise some ability to use the superior oblique eye muscle.
