nodes of Ranvier,Ranvier's nodes- small gaps in the myelin sheath of medullated axons oligodendria,oligodendroglia- tissue consisting of glial cells with sheetlike processes that form the myelin sheath of nerve fibers medulla,myelin,myeline- a white fatty substance that forms a medullary sheath...
Under electron microscopy, the myelin sheath could be seen between a vestibular ganglion cell body and a Schwann cell and consisted of 37 major lines in bats, and of about 10 in rabbits. The structure thus depends on species. The myelin sheath of human vestibular ganglion cells was seen in ...

aThe individual myelin layers can be seen in this electron micrograph of a cross section of anaxon (AX). The myelin sheath is formed by an adjacent supportive(glial) cell (SC). 各自的myelin层数在anaxon轴的横断面的这张电子显微照片能看 ()。 髓鞘由毗邻支援(神经胶质细胞) SC. (形成) [...
Myelin and Your Nerves 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 qui...

Myelin hasa high membrane resistance: Resistance– the degree to which a membrane prevents or facilitates free movement of ions. A low resistance membrane allows lots of ion movement, and a high resistance membrane does not. This occurs because the myelin sheath inhibits ion movement along the ins...
Oligodendrocyte units corresponded to classically described type I/II or type III/IV unit phenotypes which respectively myelinated discrete populations of small and large diameter axons, delineated by a myelinated fire diameter of 2–4 μm (diameter of the axon plus its myelin sheath). Within ...
The neuron is a specialised type of cell involved in the transmission of electrical signals and is the functional unit of the brain and the nervous system. The neuron consists of a cell body, dendrites, axon, and synaptic terminal, and the sheath myelin that surrounds the ax...
