When an arm is flexed, the primary activity involves the contraction of the biceps brachii muscle, which pulls the forearm towards the shoulder. This action is often accompanied by the relaxation of the triceps muscle, allowing for smooth movement. Flexing the arm also engages stabilizing muscles in the shoulder and upper back to maintain posture and control during the motion. Additionally, this movement can be associated with various activities, such as lifting objects or performing exercises like bicep curls.
