Special terms are used to describe structures associated with skeletal muscle tissue. Each segment of the sarcoplasmic reticulum forms a cufflike structure surrounding a myofibril, the fine contractile fibres that extend the length of striated muscle cells. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins. An increase in Ca 2 +-ATPase activity has been linked to the increased function of the sarcoplasmic reticulum (Mahony and Jones, 1986; Mahony, 1988). The transverse (T) tubules consist of invaginations of the sarcolemma that penetrate into the sarcoplasm so that they lie alongside and contact the . It is important in mediating muscle contraction as well as terminating muscle contraction. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins. The sarcoplasmic reticulum is a specialized endoplasmic reticulum found in muscle cells. The immature heart has an underdeveloped sarcoplasmic reticulum. what is the function of t-tubules. Calcium ion levels are kept relatively constant, with the concentration of calcium ions within a cell being 10,000 times smaller . The sarcoplasmic reticulum is continuous with the plasma membrane and forms transverse tubules. -Function is to allow electrical impulses traveling along the sarcomere to move deeper into the cell.
