Myelin is a concentrically laminated membrane structure surrounding an axon around which lamellae (or cellular protrusions) repeat radially at a period of about 12 nm (Waxman, Kocsis & Stys 1995 ...

"Understanding the structure of axons is important for understanding brain cell signaling," says Shigeki Watanabe, Ph.D., ...

Their findings, published in Nature Neuroscience, contrast with the classical view of tubular axons. 2 The researchers propose that this shape is a ubiquitous feature in all unmyelinated axons; ...

When the neuron is triggered, it activates voltage-gated sodium channels at the beginning of the axon. This causes an influx of positive sodium ions into the cell, raising the voltage and depolarizing ...

The plasma membrane of Schwann cells, which contains high amount of lipid, forms the myelin sheath. ... Any injury to the axon can lead to cell death and axonal degeneration.

Since the early part of the 20th century, scientists have been trying to better understand the intricacies surrounding neuronal development. In particular, the process by which glial cells ...

The permanent neurological deficits of multiple sclerosis patients largely depend on the extent of degeneration of long nerve fibers. The latter is initiated by ruptures in the cell membrane and ...

This sliding can increase or decrease tension in the cell. Other researchers have suggested that actin in axon terminals acts as a kind of scaffold that holds the vesicles near the synapse, Saif said.

Myosin Va and Endoplasmic Reticulum Calcium Channel Complex Regulates Membrane Export during Axon Guidance. Cell Reports , 2016; DOI: 10.1016/j.celrep.2016.04.021 Cite This Page : ...
