(A) Illustration of myelinated nerve fiber and saltatory conduction of action potential. An example of PNS myelinated nerve fiber is shown. (B) Illustration of transverse section of myelinated axon at ...

The following text summarizes information provided in the video. There are 12 pairs of cranial nerves that emerge directly from the brain and are responsible for many functions, including movement and ...

There are 12 cranial nerves in the body, all originating in the brain. They come in pairs and connect different body areas and organs to the brain. Cranial nerves can transmit two types of information ...

Results of a small study of people with tingling pain in their hands and feet have added to evidence that so-called prediabetes is more damaging to motor nerves than once believed, report scientists.

Nerves release a protein at the injury site that attracts growing nerve fibers and thus keeps them entrapped there. This prevents them from growing in the right direction to bridge the injury. The ...

Researchers have deciphered new mechanisms that enable the regeneration of nerve fibers. This could open up new treatment approaches for the brain, optic nerve, and spinal cord injuries. Injuries to ...

Small fiber neuropathy occurs as a result of damage to the small fibers of the peripheral nervous system. Damage to the peripheral nervous system that affects the small fibers can cause burning pain ...

A: The brain sends/receives electric signals that control/sense different muscles and body functions/sensory signals. These electrical signals travel either directly from the brain to the signal ...

Small diameter nerve fibers reach out to the surface of the skin, and their damage is often marked by development of burning pain in the feet. But routine nerve tests, like nerve conduction, and ...
