myelinization /my·elin·i·za·tion/ (mi″ĕ-lin″ĭ-za´shun) the act of adding myelin; formation of a myelin sheath.
myelinization [mī′əlin′īzā′shən] Etymology: Gk, myelos + izein, to cause development of the myelin sheath around a nerve fiber. Also called myelinogenesis. myelinization [mi″ĕ-lin″ĭ-za´shun] production of myelin around an axon. Called also myelination.
myelination, myelinization production of myelin around an axon. Patient discussion about myelinization. Q. What is Myelin? A. Myelin is a phospholipid layer that surrounds only the axons of many neurons. The main role of a myelin layer (or sheath) is an increase in the speed at which impulses pass along the myelinated fiber. Demyelination is the act of demyelinating, or the loss of the myelin sheath insulating the nerves, and is the cause of some neurodegenerative autoimmune diseases, including multiple sclerosis, acute disseminated encephalomyelitis, transverse myelitis, Alexander's disease, chronic inflammatory demyelinating polyneuropathy, Guillain-Barré Syndrome and central pontine myelinosis.

They may perturb commitment of neural stem cells, proliferation of neuronal progenitor cells, cell migration, synaptogenesis, cell death, formation of transmitters and receptors, trimming of connections, myelinization, and development of the blood-brain barrier (BBB). One of the ways HIV does damage is not just by replicating, but by a bystander effect on myelinization," he explained. Readiness Brazelton's (1962) model of toilet-readiness describes three physiological/maturational criteria that should precede the initiation of training: 1) voluntary control over bladder and bowel reflex actions, emerging at approximately 9 months of age; 2) the ability to cooperate with training, at approximately 12-15 months; and 3) myelinization of the pyramidal tracts of the central nervous system, at approximately 18 months. |
