Solution 1
In the bending of the elbow, the biceps brachii is the prime mover. This muscle contracts, causing the elbow to bend. The triceps brachii acts as the antagonist, meaning it relaxes to allow the movement. The brachialis also aids in this movement, but the biceps brachii is the main muscle responsible.
Solution 2
In the bending of the elbow, the biceps brachii is the prime mover. This muscle contracts, causing the elbow to bend. The triceps brachii acts as the antagonist in this action, meaning it relaxes to allow the elbow to bend. The brachialis also aids in this movement, but the biceps brachii is the main muscle responsible. Therefore, the correct answer is "biceps brachii is the prime mover."
