WebThe muscle is made up of smaller bundles known as fascicles. Fascicles are actually bundles of individual muscle cells (myofibers or myocytes). These bundles are surrounded by a connective tissue sheath called the perimysium. Each fascicle is made up of several muscle cells known as myocytes. They may also be called myofibers or muscle fibers.
