Answer 1

Answer: muscles that produce the desired action is called agonist or prime mover and the muscles that helps it is synergist muscle.

Step-by-step explanation:

Agonist or prime mover are muscles that cause a movement to occur by contracting and its activation. For example during forearm flexion, lifting up a cup involves the contraction of muscle and that muscle is the prime mover.

Synergists muscles are muscles which help the prime mover to perform their movement by reducing unnecessary movement . when the prime mover contracts, the synergist muscle stabilize it.
