Which type of muscle is found in the heart?

The heart is comprised of a specific type of muscle known as cardiac muscle, which is classified as involuntary muscle. This means that the heart operates autonomously and is not under conscious control, allowing it to continuously pump blood throughout the body without requiring active thought. The autonomic nervous system regulates this involuntary action, ensuring that heart rate and rhythm adjust according to the body’s needs, such as during exercise or rest.

While cardiac muscle is also striated in appearance, the distinction of it being involuntary is crucial in understanding its function and classification. Unlike skeletal muscle, which is voluntarily controlled and responsible for movements like walking and lifting, cardiac muscle works independently of conscious movement. This unique characteristic enables the heart to maintain its vital role in circulation continuously.
