Blood Vessels of the Arm, Anterior View

Description

Running from the axilla into the brachium, the axillary artery continues as the brachial artery along the anterior compartment, paired with the brachial venae comitantes and lying medial to the humerus before reaching the cubital fossa. Distally, the brachial artery divides into the radial artery laterally along the radius and the ulnar artery medially along the ulna, with venous channels paralleling them and digital veins forming an anterior network over the phalanges. Superficially, the cephalic vein tracks along the lateral forearm and arm, while the basilic vein ascends on the medial side, the median cubital vein bridging them across the anterior elbow. Bony landmarks include the scapula, humerus, radius, ulna, carpals, metacarpals, and phalanges. Clear landmarks. An anterior vascular map of the upper limb matters because it aligns with how clinicians access, compress, and interpret vessels on physical exam and during procedures, from brachial artery palpation and blood pressure cuff placement to arterial line planning at the wrist. The median cubital vein at the cubital fossa is the classic venipuncture target, yet its relationship to the underlying brachial artery and bicipital aponeurosis explains why misplacement or deep probing can cause arterial puncture or hematoma. This view also supports teaching of collateral pathways around the elbow and the clinical logic behind choosing cephalic versus basilic access for peripheral cannulation. Use this artwork in gross anatomy and vascular anatomy teaching to reinforce the continuity from axillary to brachial to radial and ulnar arteries, and in nursing and phlebotomy training materials focused on safe venipuncture at the cubital fossa. It also suits clinical procedure guides for peripheral IV placement, arterial sampling, and preoperative planning where surface anatomy is tied to deep vascular course.
