The g-ratio is the ratio of the axonal diameter divided by the diameter of the axon and its myelin sheath. Most myelinated axons in any given animal have the same g-ratio and this value is usually ...

Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon. This myelination, as it is ...

The myelin sheath wraps around the fibers, which are the long, threadlike parts of a nerve cell. The sheath protects these fibers, known as axons, like the insulation around an electrical wire.

Efficient removal of abnormal myelin allows survival of nerve fibers targeted by adaptive immune cells, according to a novel study. Myelin is an insulating sheath around axons -- the processes ...

Connections between neurons are called axons—long structures akin to electrical wires—and covering them is a coating ("sheath") made of myelin, a white tissue made of lipids. Comprised of up ...

A biological pathway through which myelin, the protective coating on nerve fibers, can be repaired and regenerated has been discovered in a new study. The ramifications of this finding could be ...

Support of myelinated axons through a myelin sheath requires that the architecture of myelin be intact, including the tight communication channels between the oligodendrocytes and axons.

This involves the formation of a biomembrane that wraps around the axon and significantly accelerates the speed of signal transmission. The thicker this myelin sheath, the faster the transmission.

Once the receptor is blocked, the oligodendrocytes spring into action, wrapping themselves around the axons to form a new myelin sheath. It was crucial to prove that the receptor, known as M1R, was ...

Support of myelinated axons through a myelin sheath requires that the architecture of myelin be intact, including the tight communication channels between the oligodendrocytes and axons. “When ...

Myelin is an insulating sheath around axons - the processes connecting nerve cells - that is mostly composed of lipids and proteins. It enables rapid conduction of electrical signals and supports ...
