Answer:
Schwann cells (neurolemmocyte)
Explanation:
Schwann cells (neurolemmocytes) are a type of glial cells called by the name of a German scientist, Theodor Schwann. In peripheral nervous system axons, Schwann cells allow the transduction of electrical signals from the dendrites to the axon terminals, by wrapping the plasma membrane concentrically along the axon known as the myelin sheath. In the central nervous system, the myelin sheath is formed by oligodendrocytes.
Schwann cells as unipolar neurons, like oligodendrocytes, form myelin and neurolemma in SST. Neurolema is a smooth cytoplasmic membrane that is formed by Schwann cells that encase neuronal axon fibers in SST, both bermielin and not bermielin. Neurolema is a supporting and protective structure for axon fibers.
Myelin sheath is a layer that circles axons concentrically and consists of lipids and neurokeratin. In the central nervous system myelin sheath is formed by oligodendroglia cells while in the peripheral nervous system is formed by Schwann cells.
In fresh circumstances the myelin sheath is very refractile and white (myelin gives white color to the substance of the brain alba and the spinal cord). Myelin, which mainly consists of lipids, dissolves after the usual methods of fixation, leaving a webbing of protein ingredients called neurokeratin around nerve fibers. Myelin can be fixed and black osmium tetraoxide black. After fixation with bichromate, myelin can be stained with hematoxylin
