Introduction What Muscles Are Antagonists Of The Triceps Brachii: The biceps brachii, commonly known as the biceps, is the primary antagonist of the triceps brachii. It is a two-headed muscle located on the front of the upper arm. While the triceps are responsible for extending the arm at the elbow joint, the biceps’ main function is to flex the arm at the elbow. When you perform actions like bending your arm to lift a weight or bring food to your mouth, the biceps contract to create this movement. Situated beneath the biceps brachii, the brachialis muscle also functions as an antagonist to the triceps. Its primary role is elbow flexion, similar to the biceps. It plays a crucial role in flexing the arm when performing actions that require power, such as lifting heavy objects. The brachialis is often engaged when the biceps are fully contracted and can provide additional strength during arm flexion. The brachioradialis muscle is another muscle in the forearm that acts as an antagonist to the triceps brachii. Unlike the biceps and brachialis, which are primarily responsible …
