What are the different types of muscle?
Muscles are complex structures that cause movement in the body. There are three types of muscle in the body:
- Heart muscle pumps blood (cardiac muscle).
- Skeletal muscle moves the external body parts, like the arms and legs, neck, back, trunk, and the face.
- Smooth muscle moves portions of hollow structures inside the body. Examples include the muscles that line the esophagus, stomach, and intestines, muscles that line large arteries, and the muscles of the uterus.
