​

Answer 1

The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.

Answer 2

Answer :

• Antagonist muscles act as opposing muscles to agonists, usually contracting as a means of returning the limb to its original, resting position.

• The majority of muscles are grouped in pairs, with an antagonist to each agonist muscle.

• During flexing of the forearm, the triceps brachii is the antagonist muscle, resisting the movement of the forearm up towards the shoulder$.$
