The ultrastructure of the myelin sheath in the demyelinization region of peripheral nerve fibres and their mode of shedding the myelin sheath is described in the light of an electron microscopial analysis.doi:10.1016/0014-4827(58)90200-3H. Engstr?m...
Observing the structure and regeneration of the myelin sheath in peripheral nerves following injury and during repair would help in understanding the pathogenesis and treatment of neurological diseases caused by an abnormal myelin sheath. In the present study, transmission electron microscopy, immunofluoresce...
The myelin sheath is an essential, multilayered membrane structure that insulates axons, enabling the rapid transmission of nerve impulses. The tetraspan myelin proteolipid protein (PLP) is the most abundant protein of compact myelin in the central nervous system (CNS). The integral membrane protein...
Immunohistochemical analyses reveal marked decreases in myelin basic protein intensity and myelinated fiber density in ZikV-exposed animals. At the ultrastructural level, the myelin sheath in ZikV-exposed animals shows multi-focal decompaction, occurring concomitant with dysregulation of oligodendrocyte gene...

This is supported by MBP immunohistochemistry and molecular evidence of higher MBP mRNA expression, and the expression of genes involved in the regulation of myelin sheath formation and, of proliferation and differentiation of OPCs. Additionally, WM structure correlated with cortical activity as measured...

Occasional densities reminiscent of the "radial component" can be seen. Otherwise, this structure, which is prominent in wild-type myelin, is conspicuously absent. Redundant folding of some lamellae but not others may occur in the same sheath. These observations conform to those made previously on...
Answer to: Briefly identify and describe the structure and function of the internal structures (i.e., cerebrum, diencephalon, midbrain, brain stem,...
Axon . This long, cablelike projection of the cell carries the electrochemical message (nerve impulse or action potential) along the length of the cell. Depending upon the type of neuron, axons can be covered with a thin layer of myelin sheath, like an insulated electrical wire. Myelin is ...
