The myelin sheath is crucial for the normal operation of the neurons within the nervous system: the loss of the insulation it provides can be detrimental to normal function.
WebWhite matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are … WebReduced expression of neuregulin 1 type III leads to a thinner than normal myelin sheath in the heterozygous mutant mice of this molecule.

WebThe myelin sheath, a living compacted membrane duplicature from a glial cell, helps to control the developmental, anatomical, and molecular differentiation of the axon into nodal, paranodal, juxtaparanodal, and undifferentiated internodal segments and isolates some segments of the axon electrically so that saltatory conduction becomes possible. ravenswood apartments cincinnati ohioWebNote that the myelin sheath has a lamellated structure and is surrounded by Schwann cell cytoplasm.
