Question

Quizplus · Accepted Answer

Skeletal muscles must work in pairs: the muscle that executes a given movement is the prime mover. 
The muscle that produces the opposite movement is the antagonist.
Other muscles, known as synergists, may work in cooperation with the prime mover.
The skeletal muscles, which make up the muscular system, are also called voluntary muscles because they are under conscious control.
You may use the diagram below as a visual reference for prime movers.
