Physiology

Myelinated nerve fiber

A single elongated nerve fiber shown as a thin yellow or pale cream axon wrapped in segmented myelin sheath along its length. The myelin appears as repeated sleeve-like segments or subtle elongated swellings separated by narrow constrictions representing nodes between myelin segments. The fiber remains slender, cylindrical, and slightly curved or gently wavy, with a smooth overall contour and possible slight tapering at the ends.
