MEDICAL PHYSIOLOGY

Detailed explanation-1: -The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-2: -Skeletal and cardiac muscles are known as striated muscles, because the filaments of actin and myosin that power their contraction are organized into repeating arrays, called sarcomeres, that have a striated microscopic appearance.

Detailed explanation-3: -The body possesses two types of striated muscle, cardiac and skeletal.

Detailed explanation-4: -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-5: -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.
