NEET BIOLOGY

Detailed explanation-1: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.

Detailed explanation-2: -Cardiac Muscle Function The cardiac muscle is made up of cells that are specialized for contraction and pumping. They contract in intervals to pump blood through the heart and into the rest of the body.

Detailed explanation-3: -Cardiac Muscle Tissue These are involuntary muscles and the heart pumps the blood through cardiac contractions. The cells of the cardiac muscles known as the cardiomyocytes are striated. They are single-celled and uninucleated. The ends of the cells are joined and the junctions are called intercalated discs.

Detailed explanation-4: -Cardiac muscle tissue cells are characterized by four features: they are involuntary and intrinsically regulated, striated, branched, and single nucleated.
