The biceps, deltoid, and triceps are responsible for movement in which body areas?

The biceps, deltoid, and triceps are major muscle groups that primarily facilitate movement in the arm and shoulder areas. The biceps, located at the front of the upper arm, is engaged in flexion and supination of the forearm, allowing for various movements such as lifting and pulling. The triceps, found at the back of the upper arm, is responsible for extending the elbow joint, enabling straightening of the arm. The deltoid, which caps the shoulder, plays a crucial role in raising the arm and facilitating diverse shoulder movements. Together, these muscles contribute significantly to the functionality and mobility of the upper limb and trunk, reinforcing the connection between these muscle groups and their impact on the arm and shoulder.
