Cardiac muscle, like skeletal muscle, is striated. ... differs completely from both smooth and striated muscle.Cardiac muscle tissue is only found in the heart. Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (Figure 9.6.1 9.6. 1 ).This causes the nerve cell to release acetylcholine (Ach) into the muscle cell.-The muscle cell responds to the acetylcholine (Ach) by having AP.-The muscle cell AP travels over the muscle cell membrane and down the t-tubules and causes Ca2+ to be released from the sarcoplasmic reticulum. This floods the inside of the muscle cell with Ca2+ ions.

This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary, like those of smooth muscle. Cardiac muscle, like skeletal muscle, is arranged in bundles, so it appears striated, or striped. highmark otc store catalog There are two major types of cardiac muscle cells: myocardial contractile cells and myocardial conducting cells. The myocardial contractile cells constitute the bulk (99 percent) of the cells in the atria and ventricles. Contractile cells conduct impulses and are responsible for contractions that pump blood through the body.The fundamental repeat unit within muscle that is responsible for contraction is the sarcomere. The sarcomere consists of a bundle of myosin-containing thick filaments flanked and interdigitated with bundles of actin-containing thin filaments (Fig. 1). The striated appearance of muscle results from the alternation of thick-filament-containing (A-Band) and thin-filament-containing (I-band ...
