Cranial motor axon projections are guided by diffusible cues and aided by guideposts, such as nerve exit points, glial cells and muscle primordia. The recent identification of genes that are ...

This causes an influx of positive sodium ions into the cell, raising the voltage and depolarizing the membrane. As the voltage increases along the axon, additional sodium channels open, propagating ...

the oligodendrocyte sends cell processes to myelinate multiple segments on many axons (Figure 2). Although there are several molecular or morphological differences between nerve fibers in the PNS ...

In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signal ...

An increase in high-fat, high-fructose foods in people's diets has contributed to a dramatic increase in type 2 diabetes.

It helps transmit nerve signals, or impulses, down a long axon. All neurons have a cell body. The cell body contains important structures, such as the genetic information, energy producing ...

A long fibre (axon) which is insulated by a fatty (myelin ... These receive incoming impulses from other neurones. Receptor cells detect a change in the environment (a stimulus) and start ...

However, at the junction between Schwann cells, the axon membrane is exposed ... pain sensibility within the autonomous area of the nerve S2 Return of some degree of superficial cutaneous pain ...

Myelin also protects parts of nerve cells, and damage to it can leave the axon in the nerve cell vulnerable to deterioration. Demyelination usually results from autoimmune diseases like MS and ...

Dietmar Fischer. Animal models as well as human cells have shown that cnicin significantly accelerates axon (nerve fibers) ...
