In the muscular system, an antagonist muscle acts in opposition to the action of a specific agonist muscle, relaxing and yielding while the agonist contracts. This coordinated action allows for smooth and controlled movements.
Consider a game of tug-of-war where one team pulls the rope towards themselves while the opposing team resists by pulling in the opposite direction; similarly, an antagonist muscle works by resisting the action of an agonist muscle to ensure movements are balanced and precise.
Agonist: A muscle that contracts to create movement when it shortens, working against an antagonist muscle.
Synergist: A muscle that assists the agonist in performing its action, often by providing additional force or by stabilizing joints.
Muscle Tone: The continuous and passive partial contraction of muscles or their resistance to passive stretching during resting state
