Sentences with phrase «around axons»

These produce protective sheaths that wrap around the axons of peripheral neurons.

«We looked at the optic nerve and saw normal myelination,» Mukherjee said, referring to the fatty white sheathing wrapped around axons, the nerve fibers that allow information transmission over distances to proceed efficiently and rapidly.

Axons of these nerves leave the spinal cord in the ventral branches (rami) of the spinal nerves, and then separate out as «white rami» (so called from the shiny white sheaths of myelin around each axon) which connect to two chain ganglia extending alongside the vertebral column on the left and right.

There is another class of nerve - healing substances, known as remyelinating compounds, which stimulate the repair of the protective sheath around the axon of the neurons known as myelin, and which is often damaged in neurological injury and / or dysfunction, especially autoimmune and vaccine - induced demyelination disorders.

Throughout childhood Myelin continues to be build around the axons and dendrites in your child's brain to improve the transmission of nerve signals.

They make myelin, the fatty coating around axons — long, threadlike fibers that relay neural impulses from one cell to the next, activating the circuitry that endows us with the physical and emotional capacity to fully embrace the world.

An unpredictable disease that disrupts the flow of information within the brain and between the brain and the body, MS is triggered when the immune system attacks the myelin sheath, the protective covering around the axons of nerve fibers.

Myelin twists around the axon like a jelly - roll cake and prevents the loss of electrical signals.

Myelin forms an insulating layer around these axons, the purpose of which is to allow electrical impulses to transmit efficiently and rapidly along the axonal pathways.

They then work together to build the representational brain structure, connecting all the axons by twisting a dendrite from one neuron around the axon of another, with guidance from the teacher.

Instead, supportive cells called oligodendrocytes are responsible for making the myelin sheath that wraps around axons.

Moreover, magnetic resonance imaging taken 18 months later indicated the formation of new myelin around axons and clinical observations of the treated patients indicated that their motor functions remained stable or enjoyed modest gains.

But perhaps more significant, Ind - Cl remyelinates, that is, it makes new sheaths around those axons that have not been lost for good.

RIPK1, the researchers found, inflicts damage by directly attacking the body's myelin production plants — nerve cells known as oligodendrocytes, which secrete the soft substance, rich in fat and protein that wraps around axons to support their function and shield them from damage.

Each time a network is activated — the information recalled for review or use — the connections become stronger and faster (speed through a circuit is largely determined by the layers of myelin coating that are built up around the axons — this is also in response to the flow of the electric current of information transport when the circuit is activated).

Myelin is a white fatty dielectric or electronically insulating type of material that is mainly composed of lipids and lipoproteins that wrap around axons (neurological pathways or nerves).

The more myelin around the axon, the faster the nerve cells work.
