Muscles are the connective tissues that are involved in the movement by their contraction and relaxation. Muscles are of three types - skeletal or striated, smooth muscle or non-striated and cardiac muscles.
Skeletal muscles are muscles that are part of the musculoskeletal system. They articulate with bones to carry out locomotion and movement of body parts. They are known as striated muscles due to their appearance. They are also called voluntary muscles as they can be moved at will.
Smooth or non-striated muscles lack striated bands. They are also called involuntary muscles as they regulate physiological processes such as digestion.
Cardiac muscles are specialized involuntary muscles present in the heart. They regulate heartbeat and thus, cardiac function.
