- Sarcolemma: cell membrane of the muscle fiber, containing a plasma membrane and an outer coat of polysaccharide conaining collagen fibrils; fuses with tendon fiber at the end of the muscle fiber
- Z disc: passes in the transverse plane across the myofibril to attach successive myofibrils together, enabling muscle cells to act as a syncitium and giving skeletal muscle its classic striated appearance
- Sarcomere: the portion of the myofibril that lies between two successive Z discs
- Sarcoplasm: fills spaces between myofibrils, containing potassium, magnesium, and phosphate
- Sarcoplasmic Reticulum: specialy organized reticula to control muscle contraction, site of calcium ion storage
