In the PNS, one Schwann cell forms a single myelin sheath ... The ratio between axon diameter and that of the total nerve fiber (axon and myelin) is 0.6–0.7, a ratio that is well maintained ...

MRI scans suggest runners’ brains might use the fatty substance myelin as fuel. The finding could lead to treatments for ...

As a result, myelin might not only facilitate the transmission ... spiking activity of myelinated axons in the optic nerve.

The most severe injuries have been associated with widespread axonal and myelin degeneration ... and direct nerve fiber damage, due to both axon and Schwann cell, with a breakdown in the blood ...

You disconnect your cell phone from its charger as you get ready for a busy day. But even though it has been connected all night, the battery is only partially charged. You look at ...

A single snapshot of a cell can only reveal so much. By imaging several layers in a sliver of tissue, the researchers could determine whether a nerve fiber tunneled through a cell rather than over or ...

Schwann cells, which are also known as neurolemmocytes, provide the myelin sheath that protects the axons of nerve cells. Schwann cells become active immediately after an injury and transform into ...
