axon

At this point, ~85% of these upper motor neuronal axons decussate. These fibers then descend as the lateral corticospinal tract.

Axons are the long slender projections that transmit nerve-cell impulses to the rest of the body, controlling movement.

The histomorphological analysis on the regrown axons showed that? there was no statistically significant difference between Groups B and C.

on the left side, nerve morphology was normal, nerve fibers were orderly arranged, and axons did not grow toward distal nerve.

Axons of the central nervous system in adult mammals do not regenerate spontaneously after axotomy.

The scaffold, meanwhile, supports the growth of new axons up and down the spinal cord.

He observed that the axons in his samples ended in the gray matter, and that their endings were consistent with the location of dendrites.

the lighter colored matter that lies beneath this, the region where the axons (stems of neurons) are found, is called the white matter.

Conclusion: Topical application of PEG at the early stage after spinal cord injury can effectively protect the axons from degeneration.

Although a few tortuous axons could be found, there were no irregular swelling and disconnecting axons.

A segment of a gene situated between axons that does not function in coding for protein synthesis.

"So, we saw that we could basically make axons grow over these stop signs, so that they can start to grow like a crazy driver, " he said.

Objective To explore the axonal damages in demyelination disease and its time window and morphological features of damaged axons.

Changes can be detected in bundles of thousands of axons, the fibers that carry signals.

Reduced numbers of argyrophilic neurons and vacuolar degeneration of axons were demonstrated at the myenteric plexus pathologically.

In most people, a second injury is likely to damage surviving axons and cause a more severe injury.

Like rubber insulation around electrical wires, myelin wraps around message-sending axons, protecting and speeding electrical impulses.

The result was a surprise: When PrP was present only in axons, the fibers that conduct electrical impulses, it prevented disease.

Axons Concepts develops unique projects at the leading edge of design, creativity and innovation, arts, culture, and food & beverage.

In rare cases, injury can be permanent, particularly with stretch injury that results in disrupted axons.

But when it was lacking in axons but present in the so-called Schwann cells that actually form the myelin sheath, the mice got sick.

Growing axons maintain adhesive interactions with specific environmental cues via cell adhesion molecules (CAMs).

He also believed that only axons fused by anastomosis, and that delivered nutrients from the blood vessels to neurons.

During development, axons elongate along the correct path toward their final targets.

Specialists have identified specific protein molecules in myelin that stop axons from sprouting and forming new connections.

In either case, nerve impulses "short circuit" in demyelinated axons, much like electricity in a wire whose insulation is stripped.

Anatomists surmised that the fatty covering must insulate axons like rubber sheathing along a copper wire.

Stained in black are the fiber-like extensions of the nerve cells, called axons.

It secretes guidance molecules that direct ventrally navigating axons crucial for the correct wiring of neuronal circuits.

These axons may return in dense format, and may no longer reach the areas of the bra in in which they are needed.

White matter is composed mostly of nerve fibers, called axons, which carry information between brain cells.

Fampridine-SR's major action is to block specialized potassium channels on axons.

They say the drug appears to eliminate the physical obstacles that normally prevent injured nerve cells from regrowing axons.

Sciatic pain is induced by mechanical or biological factors either by direct stimulation of axons or by neuroischemia.

This is a photomicrograph of many axons (issued from neurons growing in a dish).

Nucleus neurons in the part of core area were stellate-shaped, round nucleus and more axons.

"We already know a lot about axons -- the part of the nerve cell that is responsible for sending signals, " Rolls said.

In multiple sclerosis, for example, axons and neurons can die after myelin is lost as a result of the disease.

Experimental study of origin of the regenerating axons and effect after peripheral nerve end-to-side anastomosis in rats

We also found that glia can "listen in" on impulses shooting through axons and that the traffic heard alters the degree of myelination;
