The hand and wrist are made up of a complex network of bones, joints, muscles, tendons, and nerves that work together to perform precise movements and provide strength.

The wrist connects the hand to the forearm and is made up of eight small bones (carpals) that allow for flexibility and motion. These bones link to the metacarpals in the palm and then to the phalanges, which form the fingers and thumb.

Muscles and tendons give your hand the ability to grip, pinch, and move with control, while nerves—like the median, ulnar, and radial nerves—carry signals from the brain to power sensation and motion.

Because the hand and wrist are so intricate and constantly in use, they are especially vulnerable to injury and overuse. Understanding how they work is the first step in keeping them healthy and functioning at their best.
