The process creates a thinner myelin sheath than normal, but it helps to protect the axon from further damage, from overall degeneration, and proves to increase conductance once again. The processes underlying remyelination are under investigation in the hope of finding treatments for demyelinating diseases , such as multiple sclerosis .
Myelin's best known function is to increase the rate at which information, encoded as electrical charges, passes along the axon's length. Myelin achieves this by eliciting saltatory conduction. [1] Saltatory conduction refers to the fact that electrical impulses 'jump' along the axon, over long myelin sheaths, from one node of Ranvier to the next.
Most of the world’s top corporations have simple names. Steve Jobs named Apple while on a fruitarian diet, and found the name "fun, spirited and not intimidating." Plus, it came before Atari in ...
Myelin is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system.Therefore, the first stage of myelinogenesis is often defined as the differentiation of oligodendrocyte progenitor cells (OPCs) or Schwann cell progenitors into their mature counterparts, [4] followed by myelin formation around axons.
The two young daughters of Kamala Harris’ niece Meena Harris helped actress Kerry Washington deliver a tutorial on pronouncing the […]
The entire synapse is covered in a myelin sheath provided by the Schwann cell to insulate and encapsulate the junction. [3] Another important part of the neuromuscular system and central nervous system are the astrocytes. While originally they were thought to have only functioned as support for the neurons, they play an important role in ...
But then there have been a lot of times where it’s been the opposite, where people say, ‘You’re not African. You’re Greek. You’re ‘The Greek Freak.’ But I don’t really care about that.
For example, you may pronounce cot and caught the same, do and dew, or marry and merry. This often happens because of dialect variation (see our articles English phonology and International Phonetic Alphabet chart for English dialects). If this is the case, you will pronounce those symbols the same for other words as well. [1]
