Which type of muscle is found in the heart?

The heart is composed of cardiac muscle, which is a specialized type of involuntary muscle. Cardiac muscle is unique because it is striated like skeletal muscle but operates involuntarily, meaning it functions without the need for conscious control. This characteristic is essential for the heart's role in continuously pumping blood throughout the body. Cardiac muscle cells are interconnected, allowing for synchronized contractions that are crucial for effective heart function. This type of muscle is specifically adapted to meet the high demands of endurance and efficiency required for continuous operation, making it distinct from voluntary muscles, which are regulated by conscious thought and are typically associated with skeletal movement. Understanding this distinction is important for recognizing the different types of muscle tissue and their functions within the body.
