Study Notes
Muscles and Bones
- Muscles are attached to bones by tendons.
Muscle Pairs
- Muscles usually work a joint in pairs to allow for coordinated movement and balance.
- Muscles that work in pairs are called antagonistic muscles.
Antagonistic Muscle Pairs
- In an antagonistic pair, the muscle that is contracting is called the agonist.
- The agonist muscle opposes the movement of the antagonist muscle.
Synergistic Muscles
- Synergistic muscles assist by supporting and stabilizing the joint and the rest of the body.
- They help to refine movement and maintain posture.
