Arteries of the Arm, Anterior View

Description

Arterial channels of the upper limb are presented from an anterior perspective, beginning proximally with the axillary artery as it continues into the brachial artery along the medial aspect of the humerus. Near the cubital fossa, the brachial artery divides into the radial artery laterally and the ulnar artery medially, both descending into the forearm toward the wrist and hand. Superficial venous pathways accompany the arterial map, with the cephalic vein positioned on the anterolateral arm and forearm and the basilic vein running more anteromedially, converging proximally toward the axillary vein. Distally, the vascular tree extends into the palm, where the deep and superficial palmar arches distribute flow to the digital arteries and collect venous return through paired venae comitantes and superficial channels. Anterior arm vasculature is a daily clinical roadmap because the brachial artery lies just medial to the biceps tendon in the cubital fossa, the standard site for blood pressure measurement and a key landmark during arterial cannulation or brachial access. It is also the artery compromised in supracondylar humeral fractures, where swelling and displacement can threaten distal perfusion and precipitate Volkmann ischemic contracture if missed. Venous anatomy matters too. The cephalic and basilic veins guide peripheral IV placement and inform surgical planning for arteriovenous fistula creation or cephalic vein cutdown. Use this illustration for gross anatomy and clinical skills teaching on upper limb vascular pathways, cubital fossa relationships, and palmar arch supply, or for textbooks and patient-facing materials discussing arterial line placement, trauma assessment, and venipuncture sites. It also supports interventional and orthopedic documentation where clear laterality and proximal to distal continuity of the brachial, radial, and ulnar arteries must be communicated.
