arm

Also known as arms

In human anatomy, the arm refers to the upper limb in common usage, although academically the term specifically means the upper arm between the glenohumeral joint (shoulder joint) and the elbow joint. The distal part of the upper arm between the elbow and the radiocarpal joint (wrist joint) is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand.

AI overview

Your arm is the upper part of your limb that extends from your shoulder to your elbow, though people often use "arm" casually to refer to your entire upper limb including the forearm and hand. It matters because it's a key part of your body that enables you to reach, grasp, and manipulate objects in your environment.

By anatomical definitions, the bones, ligaments and skeletal muscles of the shoulder girdle, as well as the axilla between them, are considered parts of the upper limb, and thus also components of the arm. The Latin term brachium, which serves as a root word for naming many anatomical structures, may refer to either the upper arm as a whole or to the upper arm on its own.
