Antagonist muscles are muscles that counteract the action of agonist muscles.

Some examples of antagonist muscles are:

  • Triceps work opposite of biceps.
  • Hamstrings works opposite of quadriceps.
  • The sternocleidomastoid works opposite of the deltoids.

AN example of a synergistic muscle pair would be the biceps brachii and the brachialis muscle that work together to flex the forearm. A muscle antagonistic to those two would be the triceps brachii which functions to extend the forearm.

You can't really define a muscle as antagonistic since it's relative to another muscle known as the agonist, and this is relative to the movement. For example: in the flexion of the elbow joint the biceps brachii muscle is the agonist so the triceps brachii is the antagonist, but in extension of the elbow joint the triceps brachii is the agonist and the biceps brachii is the antagonist.

In case you don't understand, the agonist is the muscle which contracts (does the work, 'agonises') and the antagonist is the muscle which relaxes as a consequence.
