Muscles Study Guide
- The human body has 638 muscles.
- The largest muscle is in the thigh.
- The smallest muscle is in the ear.
- Muscles are made of protein.
- Muscles are controlled by the nervous system.
- Muscles make up more than 40-50% of body weight.
Voluntary Muscles
- Voluntary muscles are those you control.
Involuntary Muscles
- Involuntary muscles work automatically without conscious control.
Excitable/Irritable
- Muscles can respond to stimulation from nerves.
- Muscle response to stimulation can vary.
Flexible
- Muscles can return to their original shape and length after being stretched or contracted.
Abduction
- Moving parts away from the body.
Adduction
- Moving parts toward the body.
Extension
- Straightening the joint to increase the angle between parts.
Flexion
- Bending a joint to decrease the angle between parts.
Rotation
- Moving a body part around its axis.
Muscle Hypertrophy
- Muscle growth.
Muscle Atrophy
