An overview of neurologic assessment included the uses of vibrotactile threshold in occupational medicine (chemical exposure, hand/arm vibration, and carpal tunnel syndrome). (cdc.gov)

The impulse travels out of the spinal cord along the length of the motor nerve. (msdmanuals.com)
If the sensation occurs suddenly and is severe (as when stepping on a sharp rock or picking up a cup of very hot coffee), the impulse may travel to the spinal cord and directly back to the motor nerve, bypassing the brain. (msdmanuals.com)

The exception to this is the vagus nerve , which is the longest cranial nerve. (healthline.com)
Our center offers services ranging from routine electroencephalography, to an inpatient Epilepsy Monitoring Unit, to highly-specialized surgical treatments, including vagus nerve stimulation, responsive neurostimulation, laser ablation and traditional brain resection surgeries. (waynehealthcares.org)
Using an in vitro nerve preparation, we have studied the relative electrophysiological properties of myelinated and unmyelinated nerve fibres in the vagus nerve of 1-, 9- and 36-month-old rabbits and their sensitivity to local anaesthetic. (northwestern.edu)

Your axillary nerve starts in the fifth and sixth bones (vertebrae) in your lower cervical spine. (clevelandclinic.org)

Polyneuropathy A polyneuropathy is a diffuse peripheral nerve disorder that is not confined to the distribution of a single nerve or a single limb and typically is relatively symmetrical bilaterally. (merckmanuals.com)

Axillary nerves start in your neck at the brachial plexus (a network of nerves in your shoulder). (clevelandclinic.org)
This network of nerves enables movement and sensation to your upper limbs. (clevelandclinic.org)
Arm paralysis due to a brachial plexus (network of nerves in your shoulder) injury. (clevelandclinic.org)

Sciatic nerve pain is often characterized by a tingling sensation, sharp pain or numbness down the leg or in one area of the leg, often only on one side. (mpoi.net)

The messages are sent by chemical and electrical changes in the cells, technically called neurons , that make up the nerves. (healthline.com)
While no one knows exactly, it's safe to say humans have hundreds of nerves - and billions of neurons! (healthline.com)

A nerve corresponds to an organ of the peripheral nervous system, composed of neurons often grouped together in ganglia and projecting their axons through the tissues. (bioguideline.com)
Nerves are composed of specialized cells called neurons. (bioguideline.com)

This coordinated activity is regulated by the central and peripheral nervous systems. (medscape.com)
Neurophysiology is concerned with the investigation of function in the central and peripheral nervous system. (aspen-healthcare.co.uk)

The previous version relied on the patient reporting a sensation when the nerve fired. (wikidoc.org)

IGF-1 Levels In Pediatric Low-Grade Gliomas Overview This study investigated elevated insulin-like growth factor 1 (IGF-1) levels in children with low-grade glioma (LGG). (globalrph.com)
H-reflex study uses stimulation of a nerve and recording the reflex electrical discharge from a muscle in the limb. (wikidoc.org)
A recent study from Germany published in JAMA Network Open helps highlight a potentially beneficial role for LDL in nerve function. (dietdoctor.com)

The optic nerves are sensory nerves responsible for carrying visual information from the eyes to the brain, where it is processed to form images and visual perception. (bioguideline.com)
Typical symptoms of relapses may be referable to demyelinating pathology involving the optic nerves (e.g. optic neuritis), brainstem (e.g. internuclear ophthalmoplegia) or spinal cord (e.g. partial myelitis), although non-specific symptoms referable to the cerebral hemispheres or other brain regions can also occur (Katz Sand and Lublin, 2013).
