Muscle Types

Skeletal

Skeletal muscle moves the body, supports posture and helps with tasks such as breathing. Most skeletal muscles attach to bones; some, including facial muscles, attach to skin.

Cardiac

Cardiac muscle forms the muscular walls of the heart. Its rhythmic contractions pump blood, with its pace and strength adjusted to the body’s needs.

Smooth

Smooth muscle is found in the walls of many organs and blood vessels. It moves materials through the body and changes the diameter of passageways, usually without conscious control.
