What is the function of arms and hands?

The upper limbs are the body’s most flexible parts. Shoulder and elbow joints allow the arms to move in all directions. Attached to the arms are our versatile hands. They have countless capabilities, allowing us to touch, lift, throw, and grip. A team of muscles, tendons, and ligaments move and support these limbs.

Hand function has great significance for occupational performance. The greater the difficulties with hand function, the greater the impairment in skills that allow for independence and participation in academic and social activities.

Your arms contain many muscles that work together to allow you to perform all sorts of motions and tasks. Each of your arms is composed of your upper arm and forearm. Your upper arm extends from your shoulder to your elbow. Your forearm runs from your elbow to your wrist.
