Cardiac muscle is found only in the heart and is involuntary, meaning it operates automatically without conscious control. Its cells are striated and interconnected by intercalated discs, allowing for synchronized contractions. In contrast, skeletal muscle is attached to bones and is under voluntary control, enabling movement and posture. Skeletal muscle fibers are also striated but do not have intercalated discs, and they can contract more rapidly than cardiac muscle.
