Raising the human arm involves a complex coordination of multiple muscles, tendons, and bones. The primary muscles responsible for arm elevation are the deltoid, supraspinatus, and trapezius. These muscles work together in a precise sequence to create movement at the shoulder joint, while the biceps and triceps muscles stabilize and control the movement at the elbow joint. Additionally, the rotator cuff muscles play a crucial role in stabilizing the shoulder joint during arm elevation to prevent injury.
