- Antagonistic muscles
- What are they?
- Muscles can pull but not push,this would cause an issue if a joint was controlled
by one muscle.When the muscle had contracted and pulled on the bone,there
would be no way to move the bone back therefore our muscles are in pairs.
- Biceps and triceps are antagonistic muscles
- when the biceps muscle contracts,
the forearm moves upwards
- when the triceps muscle
contracts, the forearm
moves down
