wrist
The joint that connects your hand to your arm.
Your wrist is the joint that connects your hand to your forearm. It's what lets you wave, turn a doorknob, or dribble a basketball. Without your wrist, your hand would be stuck in one position, like a mannequin's.
The wrist is surprisingly complex: it contains eight small bones arranged in two rows, held together by ligaments and moved by tendons that run from muscles in your forearm. This design gives your hand remarkable flexibility. You can bend your wrist forward and back, tilt it side to side, and even rotate it in circles.
People wear watches, bracelets, and fitness trackers on their wrists because it's convenient and easy to see. Athletes like gymnasts, tennis players, and pianists depend on strong, flexible wrists for their skills. When someone sprains their wrist, often from falling on an outstretched hand, they discover how much they use this joint for everyday tasks like writing, eating, or opening a jar.
The phrase slap on the wrist means a mild punishment that doesn't really hurt, like getting a warning instead of serious consequences for misbehavior.
