In human anatomy, the arm is the region of the upper limb extending between the shoulder and the elbow, though in common usage the term often denotes the whole upper extremity from shoulder to hand. The arm proper is built around the humerus and is divided into anterior and posterior compartments containing the flexor muscles, chiefly biceps brachii, brachialis, and coracobrachialis, and the extensor triceps brachii, innervated respectively by the musculocutaneous and radial nerves and supplied by the brachial artery. Together with the forearm and hand, the arm provides the skeletal levers, musculotendinous units, and neurovascular pathways that enable reaching, lifting, and manipulation, and its dimensions are used anthropometrically, for example arm span as a surrogate for stature and mid-upper-arm circumference as an index of nutritional status. Clinically, the upper limb is a frequent site of trauma, neurovascular injury, and developmental anomaly. Human anatomy as a discipline studies such regional structure through dissection, imaging, and morphometric analysis, integrating gross, developmental, and clinical perspectives. While several articles in this journal's corpus address upper-limb measurement and related anthropometry, the broader description here reflects the standard anatomical understanding of the arm and its place within the upper extremity.
