Description: This painting is of a cross section of the muscle showing muscle fibers in red.. A muscle is composed of multiple bundles of cells called muscle fibers; these fibers generate the force to move our joints. Unlike other cells in the body, the muscle fibers have more than one nucleus, blue dots. The muscle fibers are organized in groups and are under the control of the nervous system. Nerve fibers, in green, course around the muscle fibers, and include those that sense painful signals.
