Web• Ca++ release from T- tubules, which are large, is a very important source of Ca++. • T-tubule Ca++ depends strongly on extracellular Ca++ concentration. • Heart’s T-tubules are bigger than those in skeletal muscle and rich in mucopolysaccharides. • Mucopolysaccharides bind and store Ca++. WebA muscle fiber is composed of many fibrils, packaged into orderly units. The striated appearance of skeletal muscle tissue is a result of repeating bands of the proteins actin and myosin that are present along the length of myofibrils.
