Muscle Tissue

Muscle tissue is a specialized type of tissue that enables the body to move and provides support to the skeletal system. There are three main types of muscle tissue: skeletal, smooth, and cardiac.

Skeletal Muscle Tissue

Skeletal muscle tissue is attached to the bones of the skeletal system and is responsible for voluntary movements such as walking, running, and lifting objects. It is striated in appearance due to the arrangement of actin and myosin filaments, and is under conscious control.

Smooth Muscle Tissue

Smooth muscle tissue is found in the walls of internal organs such as the stomach, intestines, and blood vessels. It is non-striated and is responsible for involuntary movements such as peristalsis in the digestive system and regulating blood flow in the circulatory system.

Cardiac Muscle Tissue

Cardiac muscle tissue is found exclusively in the heart and is responsible for pumping blood throughout the body. It is striated like skeletal muscle but is under involuntary control, allowing the heart to beat rhythmically without conscious effort.
