Study Notes
Muscle Types
- The muscular system is comprised of roughly 600 muscles.
- Voluntary muscles are controlled by conscious effort, like the muscles in your arms and legs.
- Involuntary muscles operate without conscious control, such as the muscles in the stomach and intestines.
- Skeletal muscles are voluntary muscles attached to bones, found in the arms, legs, back, chest, and face.
- Smooth muscles are involuntary muscles found in the internal organs, such as the stomach and intestines. These muscles continuously contract and relax without conscious control.
- Cardiac muscles are found primarily in the heart walls and are involuntary, responsible for pumping blood throughout the body.
Muscle Disorders and Injuries
- Muscle Strain: Occurs when a muscle is stretched beyond its limit, causing a tear. This is also known as a pulled muscle. Common causes include accidents, overuse, or incorrect muscle usage. Muscle strains are painful.
- Muscle Cramp: An involuntary and painful contraction of a muscle that does not easily relax.
- Muscle Bruise: Occurs when a muscle impacts a hard object, causing the muscle tissue to be damaged.
