Detailed explanation-1: -Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. Cardiac muscle – the muscle specific to the heart.
Detailed explanation-2: -Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control. The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action.
Detailed explanation-3: -Skeletal muscle is an organ that primarily controls movement and posture. Cardiac muscle encompasses the heart, which keeps the human body alive. Smooth muscle is present throughout the gastrointestinal, reproductive, urinary, vascular, and respiratory systems.
