Detailed explanation-1: -Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
Detailed explanation-2: -The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action. The cardiac muscle must contract with enough force and enough blood to supply the metabolic demands of the entire body. This concept is termed cardiac output and is defined as heart rate x stroke volume.
Detailed explanation-3: -The primary function of the cardiac muscle is to regulate the functioning of the heart by the relaxation and contraction of the heart muscles. Other functions of cardiac muscles include: The cardiac muscles function as the involuntary muscle. The cardiac muscles are also involved in the movement or the locomotion.
Detailed explanation-4: -Cardiac muscle cells are branched, allowing for faster signal propagation and contraction in three dimensions. Cardiac muscles cells are not fused together, but are connected by gap junctions at intercalated discs.
Detailed explanation-5: -Cardiac and skeletal muscles are both striated muscles composed of repeated units called sarcomeres, crossed with a regular pattern of fine red and white lines giving the muscles their distinctive striated appearance and their name.
