Herein, we propose a cell vibron polariton (cell-VP): a collectively coherent mode of a photon and all phospholipid molecules in a myelin sheath which is a nervous cell majorly consisting of the phospholipid molecules. Cell-VP can be resonantly self-confined in the myelin sheath under ...
Share on Facebook myelin sheath Thesaurus Medical Encyclopedia Wikipedia n. The insulating envelope of myelin that surrounds the core of a nerve fiber or axon and facilitates the transmission of nerve impulses. In the peripheral nervous system, the sheath is formed from the membranes of Schwann ce...
What cells produce the myelin sheath?Myelin SheathThe myelin sheath wraps some neuron's axons to increase the speed at which they pass electrical signals. The myelin sheath also works to protect and insulate axons. Axons are wire-like extensions on the neuron responsible for carrying signals away...
Is the facial nerve on the medulla? Is the trigeminal nerve parasympathetic? Is the temporal nerve part of the facial nerve? Is the facial nerve connected to the lingual nerve? Do all nerves have a myelin sheath? Is the facial nerve involved with the gustatory system?
The myelin sheath wraps around the fibers, which are the long, threadlike parts of a nerve cell. The sheath protects these fibers, known as axons, like the insulation around an electrical wire. When the myelin sheath is healthy, nerve signals are sent and received quickly. But when something...
Myelination depends on the coordination of a battery of glial structural proteins that are responsible for the architecture of compact myelin. We have also reviewed a number of transcription factors that play important roles in Schwann cell differentiation and progression through the promyelinating stage...

This means that although the person has symptoms that are like the symptoms of Parkinson’s, they are not being driven by a dopamine deficiency. It may simply be that the myelin sheath coverings around the neurons are clogged by toxins or obstructed by trauma to the tissues. Or, other facto...
Upon completion of radial sorting, promyelinating SCs are associated 1:1 with large-caliber axons (>1 μm in diameter), whereupon they initiate formation of a myelin sheath. In contrast, multiple small-caliber axons in peripheral nerves are ensheathed by non-myelinating Remak SCs into Remak...
The present study demonstrates how lack of myelination impacts synaptic function in the cerebellum using theLESrat, which has a genetic deletion of myelin basic protein (MBP) and fails to condense the myelin sheath18,19. Axons from youngLESrats before postnatal 4 weeks are loosely covered by 2...
