Musculoskeletal Words
- 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
