Verified step by step guidance

Understand the concept of antagonistic muscles: In anatomy, antagonistic muscles are pairs of muscles that work against each other to create movement. When one muscle contracts, the other muscle relaxes, allowing for controlled movement.

Identify the role of antagonistic muscles: These muscles are crucial for maintaining balance and posture, as they allow for precise control of movements by opposing the action of the primary muscle involved in a movement.

Analyze the options given: Review each option to determine which one correctly describes the function of an antagonistic muscle.

Option A describes a synergistic muscle, which assists another muscle in performing a movement. Option B describes an agonist muscle, which is primarily responsible for a specific movement. Option D describes a stabilizer muscle, which helps maintain the position of a joint or origin of another muscle.

Recognize that the correct definition of an antagonistic muscle is: A muscle that opposes the action of another muscle, as it provides the necessary resistance to control the movement initiated by the agonist muscle.
