WebMyelination is tightly controlled by axons. Only medium and large diameter axons are myelinated, and thin axons (smaller than 1 μm) are ensheathed by nonmyelinating Schwann cells and are organized in bundles (called Remak bundles; Hillarp & Olivecrona, 1946). Thin and thick myelinated axons have thin and thick myelin sheaths, respectively. WebThe main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated fiber. In unmyelinated …
