myelinated , także: medullated

Ten times as many can be delivered by the large myelinated nerve fibers.

Some studies suggest an overall decrease in the number of myelinated fibers.

Marked loss of myelinated nerve fibers in the human brain with age.

Between about two months before and after birth, most of the cerebral cortex becomes myelinated.

In peripheral nerves there is a loss of large myelinated fibres.

This myelinated division can then enter the sympathetic chain.

The gelatinous appearance is due to a very low concentration of myelinated fibers.

White matter is composed mainly of myelinated axons, and takes its color from the myelin.

In some cases, patients have shown mental retardation and loss of myelinated axons.

Mycotoxins can directly affect the long myelinated nerves in the hind limbs.

Recently, skin biopsy has been used to investigate mechanoreceptors and their myelinated afferents.

Men have slightly more white matter than females both in volume and in length of myelinated axons.

White matter consists mostly of myelinated axons:.

Myelin prevents ions from entering or leaving the axon along myelinated segments.

Action potentials cannot propagate through the membrane in myelinated segments of the axon.

In myelinated axons, Schwann cells form the myelin sheath (see above).

In the mammalian myelinated nerve, the impulse travels at a velocity of about 100 meters per second, or, if you prefer, 225 miles an hour.

This protein is localized at the juxtaparanodes of myelinated axons and associated with potassium channels.

The length of axons' myelinated segments is important to the success of saltatory conduction.

Saltatory conduction has also been found in the small- and medium-sized myelinated fibers of Penaeus shrimp.

It would, therefore, make sense if axons played a part in controlling the number of oligodendrocytes that develop in a myelinated tract.

Histopathology of peripheral nerve shows reduced number of myelinated and non-myelinated axons.

Saltatory conduction is defined as an action potential moving in discrete jumps down a myelinated axon.

Fibers of the A group have a large diameter and high conduction velocity, and are myelinated fibers.

The main purpose of a myelin layer (or sheath) is to increase the speed at which impulses propagate along the myelinated fiber.
