Surrounding each muscle fiber (cell) is a delicate external lamina composed primarily of reticular fibers. This external lamina is produced by the muscle fiber and, when observed through the light microscope, cannot be distinguished from the cell membrane of the muscle fiber, the sarcolemma.
The connective tissue sheath surrounding each fasciculus is the perymysium. Finally, by cutting through the perimysium and using a microscope, one would see the muscle fibers, which are the individual muscle cells. A sheath of connective tissue, called the endomysium, also covers each muscle fiber. It is generally thought that muscle fibers extend from one end of the muscle to the other; but under the microscope, muscle bellies often divide into compartments or more transverse fibrous bands(inscriptions).
