Answer:
Prime mover
Step-by-step explanation:
The term "prime mover" refers to the main muscle that is responsible for producing a particular movement. The prime mover is the muscle that is primarily responsible for the action, and it typically works in conjunction with other muscles, called synergists, that help to stabilize or support the movement. The opposing muscle that works to resist or oppose the movement is referred to as the antagonist. The prime mover and its synergists are sometimes referred to collectively as the agonist muscles. Understanding the role of the prime mover is important in understanding how movements are produced and how they can be improved or altered through strength training or rehabilitation.
