Sentences with phrase «myelin around each axon»

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.
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.

Not exact matches

Throughout childhood Myelin continues to be build around the axons and dendrites in your child's brain to improve the transmission of nerve signals.
In the AIDP variant of Guillain - Barré syndrome, the focus of the autoimmune attack is the myelin sheath, a layer of insulation that surrounds nerve axons, similar to the insulation around the wires of an electric cable.
The other is that the virus itself directly attacks neural cells and destabilizes the myelin sheath around them or damages axons to cause GBS.
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.
Those signals are disrupted because myelin, the insulating sheath around a nerve cell's message - transmitting axons, becomes damaged.
The brain creates new oligodendrocytes that wrap fresh myelin around the affected axons, Popko and colleagues reported in January 2016 in Nature Neuroscience.
OLs formed before tamoxifen injection are red, newly - forming OLs have a yellow «cell body» containing the nucleus surrounded by a green «bundle of sticks» which are short stretches of myelin wrapped around thread - like axons.
Instead, supportive cells called oligodendrocytes are responsible for making the myelin sheath that wraps around axons.
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.
The genes in question are all involved in the production of myelin, which forms the fatty insulation around nerve cell axons that enables efficient communication in the central nervous system.
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.
In the peripheral nervous system, myelin forms when «membrane tongues» extend from Schwann cells to spirally wrap around an adjacent axon.
Myelin twists around the axon like a jelly - roll cake and prevents the loss of electrical signals.
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 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.
