Myasthenia gravis is defined as adisease in which the immune system attacks the acetylcholine receptors at the nerve-muscle junctions.

Myelencephalon is one of the five (5) principal divisions of the brain part of the brainstem.

Myelin is defined as a fatty layer which coats some axons; an insulating material composed of fats and proteins. a fatty substance coating the axons of some neurons that facilitates the speed and accuracy of neuronal communication Moreover, Myelin is a lipid sheath that surrounds and insulates the axons of the central and peripheral nervous systems. It serves to increase the speed of nerve conduction; fatty sheath that wraps around neurons and enables them to transmit information more rapidly. Please see also Myelin sheath

Myelin sheath is an insulating material that covers many vertebrate axons; fatty-type covering of axons that increases the speed of axonal transmission; sheet of fatty substance that develops around the neurons to promote faster transmission of electrical signals through the nervous system. Please see also Myelin .

Myelin staining are selectively dyes the sheaths of Myelinated axons. As a result, white matter, which consists of myelinated axons, stains black, unlike other areas of the brain that consist mostly of cell bodies and nuclei.

Myelinated axon is axon covered with a Myelin sheath

Myelination is defined as development of a Myelin sheath that insulates an axon; development of myelin around neurons, which proceeds at different rates in different areas of the brain.

Myelinization refers to the process by which neurons are enclosed in waxy Myelin sheaths that will facilitate the transmission of neural impulses.
