Schwann cell - Named after the German physiologist Theodor Schwann, Schwann cells are a variety of neuroglia that mainly provide myelin insulation to axons in the peripheral nervous system of jawed vertebrates. The vertebrate nervous system relies on this myelin sheath for insulation and as a method of decreasing membrane capacitance in the axon, thus allowing for saltatory conduction to occur and for a an increase in impulse speed, without an increase in axonal diameter.
Neurolemma - Neurolemma (spelled also neurolema, neurilemma and neurilema, and sometimes used interchangeably with epineurium) is the insulating myelin layer that surrounds an individual peripheral nerve fiber. The myelin is contributed by Schwann cells and the layer is sometimes referred to as the sheath of Schwann.
Leukodystrophy - Leukodystrophy refers to progressive degeneration of the white matter of the brain due to imperfect growth or development of the myelin sheath, the fatty covering that acts as an insulator around nerve fiber. Myelin, which lends its color to the white matter of the brain, is a complex substance made up of at least ten different chemicals.
Motor end plate - ... motor end plate is the distal (farthest from the nerve body) end of the nerve where the nerve impulse causes emission of acetylcholine molecules into the synaptic cleft to innervate muscle fibers triggering muscle contraction. A motor (efferent) nerve axon loses its myelin sheath and branches into multiple endings, which occupy depressions in the sarcolemma.
