Occipital nerve. It is the second cranial nerve.
How can one improve the function of the vagus nerve?
Improving the function of the vagus nerve can be done through techniques like deep breathing, meditation, yoga, and regular exercise. These activities can help stimulate the vagus nerve and promote overall well-being.
What is the small gap between neurons called?
The small microscopic gabs b/w the two neurons are called "Synapse". The conduction of nerve impulse through this synapse is made possible through Neurotransmitters. As the impulse reaches at the Pre-synaptic membrane the small vesicles release these Neurotransmitters which initialize the impulse in post-synaptic membrane.
Why do scientists want to get mature nerve cells to divide?
Mature cells can't grow back, in other words divide or reproduce. This means that when a person gets severe burns, or brain damage, the cells won't come back and the person might be paralyzed or have no feeling in a certain area. So if it was possible for nerve cells to divide, they person wouldn't have any problems and could heal themselves.
How long does it take for a tooth nerve to die?
While in a tooth or after pulled? Inside your tooth in your mouth, the nerve may not die. You may have to get a root canal done to remove the nerve and keep the tooth. If a person does not pull an infected tooth, the infection may strangle the nerve and leave a non-sensitive tooth. You will then have a grey tooth with no life in it. If this happens and your lucky enough without medication so as the infection goes away; you would have experienced a natural root death and will need to keep an eye on the tooth and get x rays done often. Your tooth will still rot and you will not know it because you feel little pain in the tooth. If your talking about the nerve in the pulled tooth's orifice, bottom jaws could be damaged for months or even permanently. You may also feel as though your lip was numb if you have damage. Top back orifices may perforate the nasal cavity and may hurt constantly. Please be more specific for specific answers.

Femoral nerve dysfunction?
DefinitionFemoral nerve dysfunction is a loss of movement or sensation in the leg due to nerve damage.See also: Peripheral neuropathy; Mononeuropathy; Mononeuritis multiplexAlternative NamesNeuropathy - femoral nerve; Femoral neuropathyCauses, incidence, and risk factorsThe femoral nerve is located in the leg. It supplies the muscles that help straighten the leg. It provides feeling (sensation) to the front of the thigh and part of the lower leg.A nerve is made up of many fibers, called axons, surrounded by insulation, called the myelin sheath.Damage to a nerve such as the femoral nerve is called mononeuropathy. Mononeuropathy usually means there is a local cause of the nerve damage, although disorders that involve the entire body (systemic disorders) can also cause isolated nerve damage (such as occurs with mononeuritis multiplex).The usual causes of femoral nerve dysfunction are direct injury (trauma), prolonged pressure on the nerve, and compression of the nerve by nearby parts of the body or disease-related structures (such as a tumor). Prolonged pressure may lead to a lack of oxygen because there is decreased blood flow (ischemia) in the area. This lack of oxygen can cause further complications.Entrapment involves pressure on the nerve where it passes through a narrow structure (for example, as it passes through a muscle). The damage includes destruction of the insulation around the nerve (the myelin sheath) or destruction of part of the fibers themselves (the axon). This damage slows or prevents nerve impulses from passing through the nerve.The femoral nerve can be injured due to breaking bones of the pelvis. It can be injured when a catheter is placed in the artery in the groin (femoral artery), which lies next to the nerve. It can be one of many nerves affected by diseases causing widespread nerve damage (polyneuropathy), such as diabetes. It also can be damaged by pressure from tumors, abscesses, or internal bleeding into the pelvis or abdomen.One common risk factor is lying on the back with the thighs and legs flexed ("lithotomy" position) during surgery or diagnostic procedures. Branches of the femoral nerve can be compressed by tight or heavy waist belts. In some cases, no cause can be found.SymptomsSensation changes in the thigh, knee, or leg, such as decreased sensation, numbness, tingling, burning, a feeling of the knee "giving way" or buckling, or (uncommonly) painWeakness of the knee or leg, including difficulty going up and down stairs -- especially downSigns and testsAn exam of the nerves and muscles (neuromuscular exam) of the legs shows that the femoral nerve is not working well. You might have weakness when you straighten the knee or bend at the hip. Sensation changes are located on the front of the thigh and inner calf. The knee reflex may be decreased or absent. The quadriceps muscles on the front of the thigh may be smaller than normal.Tests that reveal femoral nerve dysfunction may include:Electromyography (EMG)Nerve conduction tests (NCV, usually done at the same time as an EMG)MRI to check for masses or abnormal tissue (lesions)You'll have tests based on the suspected cause of the problem, which the doctor will base on your medical history, symptoms, and the pattern of symptom development. These tests may include various blood tests, x-rays, scans, or other tests.TreatmentYour doctor will try to identify and treat the cause of the nerve damage. In some cases, no treatment is required and you'll recover on your own. In that case, any treatment is aimed at increasing mobility and independence while you recover.Supportive treatment is usually given if the symptoms come on suddenly, if there is only minor sensation or movement changes, no history of trauma to the area, and no sign that nerve function is getting worse.Other treatments include:Corticosteroids injected into the area to control obvious swelling or inflammation.Pain medication, if necessary. Various other medications can reduce the stabbing pains that some people experience. The benefits of medications should be weighed against any possible side effects.Some people might benefit from surgical removal of tumors or other growths that press on the nerve.Physical therapy may be helpful to maintain muscle strength. Orthopedic appliances such as braces or splints may help in walking. Your health care provider might recommend vocational counseling, occupational therapy, job changes or retraining, or similar interventions.Expectations (prognosis)If the cause of the femoral nerve dysfunction can be identified and successfully treated, it is possible to recover fully. In some cases, there may be partial or complete loss of movement or sensation resulting in some degree of permanent disability.Nerve pain may be quite uncomfortable and can continue for a long time. Injury to the femoral area may also injure the femoral artery or vein, which can cause bleeding and other problems.ComplicationsWhen there is a loss of feeling (sensation), a potential complication is repeated and unnoticed injury to the leg. When there is muscle weakness, falls and related injuries may occur.Calling your health care providerCall your health care provider if you develop symptoms of femoral nerve dysfunction.PreventionPrevention depends on the cause of the nerve damage.ReferencesMisulis KE.

What is the gap between neurons called in the human nervous system?
This gap is called the synapse. It takes something to cross it to stimulate the next nerve cell to carry the information to it's destination. This would either be a neurotransmitter or an ion. Blocking the gap stops the information. If you get a nerve block so surgery can be done, this is what happens.
How does the work done on a sliding block with friction affect its potential energy?
When work is done on a sliding block with friction, it can either increase or decrease the block's potential energy, depending on the direction of the force applied. If the work is done against the force of friction, the potential energy of the block increases. Conversely, if the work is done in the direction of the force of friction, the potential energy of the block decreases.
What important work is done by the nerve?
carry messages to the brain
How do you calculate the work of a block on an incline?
The work done by a block on an incline is calculated using the equation: work = force * distance * cos(theta), where force is the component of the weight of the block that acts parallel to the incline, distance is the displacement of the block along the incline, and theta is the angle between the force and the displacement vectors.
How much work is done when an 8 N force moves a block 7 meters?
The work done is calculated as the product of the force applied and the distance moved in the direction of the force. In this case, the work done is ( 8 , N \times 7 , m = 56 , J. )
What nerve carries signals from the from the retina to the brain?
Occipital nerve. It is the second cranial nerve.

What is nerve ablation?
Nerve ablation is a medical procedure that involves using heat, cold, or chemicals to destroy a nerve, usually to reduce pain or other symptoms associated with the nerve. It is often done for chronic pain conditions when other treatments have not been effective. The goal of nerve ablation is to interrupt the pain signals being sent from the nerve to the brain.
How far will 350 J raise a block weighing 7 N?
The work done on the block is 350 J, which can be used to raise the block against gravity. Work done = force x distance. So, distance raised = work done / force = 350 J / 7 N = 50 meters.
How much work will you will have done if you lift a block 2 m?
The amount of work done in lifting a block is equal to the force applied multiplied by the distance over which the force is applied (W = F*d). If you provide the force applied, I can calculate the work done.
