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.
a)Each muscle fiber is a long cylindrical cell with multiple nuclei (syncytial) within its plasma membrane called the sarcolemma. Within the sarcolemma of the muscle fiber is the sarcoplasm or cytoplasm of a muscle cell or fiber. The sarcoplasm differs from the cytoplasm of other cells in that it contains large amounts of glycosomes (stored glycogen) along with an oxygen binding protein called myoglobin.
