In movement, what is the term for the muscle that opposes the prime mover?

Explanation:
The opposing muscle is called the antagonist. It provides the opposite action at a joint, helping to control and smooth the movement and prevent it from happening too quickly or forcefully. For example, in a biceps curl, the biceps are the prime movers for elbow flexion, while the triceps act as the antagonist to oppose that flexion. Stabilizers hold joints in place to allow a steady movement, and synergists assist the prime mover without opposing the movement.
