Physiology

Extrafusal muscle fiber

A large, long cylindrical skeletal muscle fiber with a robust elongated form, uniform diameter, and clear transverse cross-striations along most of its length. The fiber is thicker than an intrafusal fiber, uniformly contractile, and colored pink-red with alternating light and dark bands. Multiple elongated peripheral nuclei lie just beneath the membrane.
