The type of muscle found in the heart is cardiac muscle. This specialized muscle tissue is involuntary, meaning it operates automatically without conscious control. Cardiac muscle is unique in its structure, containing striations like skeletal muscle, but its cells are interconnected through intercalated discs, allowing for synchronized contractions. This characteristic enables the heart to pump blood efficiently throughout the body. Cardiac muscle has an inherent ability to contract rhythmically and continuously, which is crucial for maintaining healthy blood circulation and supporting life.
