WebThe main purpose of a myelin layer (or sheath) is to increase in the speed at which impulses propagate along the myelinated fiber. Along unmyelinated fibers, impulses move continuously as waves, but, in myelinated fibers, they hop or "propagate by saltation ." Web[00108] Myelin: A lipid substance forming a sheath (known as the myelin sheath) around the axons of certain nerve fibers. Myelin is an electrical insulator that serves to speed the conduction of nerve impulses in nerve fibers. "Myelination" (also "myelinization") refers to the development or formation of a myelin sheath around a nerve fiber (axon). Web24 Sep 2024 · What is the function of myelin?
