What is the role of the muscular system?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

What are the 4 types of muscles?
Muscle TypesSkeletal Muscle. Skeletal muscle, attached to bones, is responsible for skeletal movements. … Smooth Muscle. Smooth muscle, found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus, is under control of the autonomic nervous system. … Cardiac Muscle.
What are the three main parts of the muscular system?

What are your muscles called?
These are your skeletal muscles — sometimes called striated (say: STRY-ay-tud) muscle because the light and dark parts of the muscle fibers make them look striped (striated is a fancy word meaning striped). Skeletal muscles are voluntary muscles, which means you can control what they do.
What is the fastest type of muscle?
The two types of skeletal muscle fibers are slow-twitch (type I) and fast-twitch (type II). Slow-twitch muscle fibers support long distance endurance activities like marathon running, while fast-twitch muscle fibers support quick, powerful movements such as sprinting or weightlifting.
What are the roles of the 3 types of muscles?
In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood.
What is the primary job of the muscles?
The primary job of muscle is to move the bones of the skeleton, but muscles also enable the heart to beat and constitute the walls of other important hollow organs.
What are 4 functions of the muscular system?

Muscle tendons stretch over joints and contribute to joint stability. … Posture. … Circulation. … Respiration. … Digestion. … Urination. … Childbirth.More items…•
What is the main organ of the muscular system?
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body.
