myelinated fiber

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

Myelinated fibers are located adjacent to the spinal central gray.

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

Both nerve conduction studies and electromyography study the large diameter myelinated fibers.

Conversely, for a given conduction velocity, myelinated fibers are smaller than their unmyelinated counterparts.

In the body, Type II fibers are the second most highly myelinated fibers.

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

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

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

The contacts between neurons and glial cells display a very high level of spatial and temporal organization in myelinated fibers.

The PCML pathway is composed of rapidly conducting, large, myelinated fibers.

By contrast, gamma motor neurons have Aγ axons, which are slender, lightly myelinated fibers that conduct less rapidly.

Alpha motor neurons have Aα axons, which are large-caliber, heavily myelinated fibers that conduct action potentials rapidly.

Synaptic complexes formed by functionally defined primary afferent units with fine myelinated fibers (co-author, 1982)

Along unmyelinated fibers, impulses move continuously as waves, but in myelinated fibers, they hop or "propagate by saltation."

The thalamus comprises a system of lamellae (made up of myelinated fibers) separating different thalamic subparts.

The alveus of the hippocampus borders the wall of the lateral ventricle and is composed of white, myelinated fibers.

Fleece of Stilling: a mesh of myelinated fibers surrounding the dentate nucleus of the cerebellum.

Lamina VI or SGP, the stratum griseum profundum ("deep gray"), consists of loosely packed neurons and myelinated fibers.

Once activated, they send action potentials through large myelinated fibers of the paired vagus nerves to the inspiratory area in the medulla and apneustic center of the pons.

The NCV shows reduced or absent sensory nerve action potentials and nerve biopsy shows total loss of myelinated fibers and reduced numbers of unmyelinated fibers.

The burning sensation was still present during a selective block of impulse conduction of A-fibres in myelinated fibers, which indicates that nociceptive C-fibres are activated by CFS.

In combination, they can provide an initial burst of pain, initiated by the faster myelinated fibers, followed by a slower and longer lasting dull pain initiated by unmyelinated fibers.

Currently, it is the only technique used to detect and quantify the pathophysiology of positive sensory phenomena mediated by large myelinated fibers and thin myelinated and unmyelinated fibers.
