Muscle cells, or fibers, are elongated cells that perform their functions by developing a tension along their longitudinal axes. Groups of muscle fibers may form fasciculi (fasciculus = small bundle), and many fasciculi, in turn, are aggregated into units we call muscles. There are several types of muscle cells.
