WebThe plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma is the site of action potential conduction, which triggers muscle contraction. Within each muscle fiber are myofibrilslong cylindrical structures that lie parallel to the muscle fiber. Read More: How is nerve transfer done? What is a muscle fiber?

WebAfter death, a person no longer makes ATP, and calcium stored in the specialized endoplasmic reticulum of muscle fibers diffuses down its concentration gradient into the muscle cytoplasm.... WebThere are two other proteins located at the plasma membrane which help to return Ca++ to its basal level inside the cardiac muscle cell. The plasma membrane CaATPase uses ATP to actively pump Ca++ out. The Na+ - Ca++ exchanger transports Na+ into the cell for each Ca++ moved out of the cell (i.e., exchanges Na+ for Ca++). Figure 4.
