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 problem Oligodendrocytes (OLs) produce the myelin sheaths that electrically insulate axons. Although most OLs are generated in the early postnatal period, oligodendrocyte progenitors (OPs) ...

Myelin is an insulating layer of lipids and proteins surrounding nerves. Myelin damage can cause problems with the nerves’ ability to send and receive electrical messages. Inflammatory disorders ...

Damage to myelin, the protective sheath surrounding nerve fibers, impairs the brain's ability to transmit signals efficiently ...

As the voltage increases along the axon, additional sodium channels open, propagating the signal. The myelin sheath made of protein and fatty substances surrounds the axons of certain nerve cells and ...

"We proposed that, during evolution, the emergence of myelin coincided with the loss of lipid droplets in axon-associated ...

A long fibre (axon) which is insulated by a fatty (myelin) sheath. They are long so they can carry messages up and down the body. Tiny branches (dendrons) which branch further as dendrites at each ...

The decrease in ion flux would negate the advantage of decreased capacitance, if the myelin sheath were continuous. However, at the junction between Schwann cells, the axon membrane is exposed.
