Check all that are true statements regarding antagonists. antagonists serve as prime movers. a muscle that is an antagonist works in conjunction with an agonist to perform its action. the stretching of the antagonist slows and controls the action of the agonist. the action of the antagonist opposes the action of the agonist.

- The stretching of the antagonist slows and controls the action of the agonist. (True)

- The action of the antagonist opposes the action of the agonist. (True) 

To achieve smooth movement, different types of muscles adopted different types of contraction and hence different functions. 

Agonist and antagonist are types of muscle functions. Agonist muscles main function is proving a major force for movement such as (bicep curl). During movement, antagonist function is opposing the agonist. The antagonist can either relax ensuring joint integrity or stop movement completely.
