Atlas of Human Anatomy by Netter

Continuation of the axillary artery, ends in cubital fossa

Lies anterior to triceps and brachialis throughout its course

Accompanied by median nerve, which crosses anterior to artery and lies medially in cubital fossa

Divides into ulnar and radial arteries under bicipital aponeurosis

Branches

Many muscular branches

Profunda brachii artery from medial aspect

Superior and inferior ulnar collateral branches

Profunda brachii (deep artery of the arm)

Accompanies radial artery in radial groove

Divides into anterior and posterior descending branches to elbow

Arterial Supply to the Forearm

Ulnar artery

Larger of two terminal branches of brachial artery

Begins medial to biceps tendon and descends through anterior compartment deep to pronator teres

Branches

Anterior ulnar recurrent

Posterior ulnar recurrent

Common interosseus, which branches into

Anterior interosseus artery

Posterior interosseus artery

Muscular branches to muscles of medial side of forearm

Branches to the hand

Radial artery

Begins in cubital fossa at neck of radius

Passes distally deep to brachioradialis muscle

Palpable throughout lateral forearm (best felt at the wrist)

Branches

Supplies flexor and extensor muscles on lateral side of forearm

Radial recurrent artery

Branches to the hand

Arterial Supply to the Hand

Branches from the ulnar artery

Palmar carpal branch

Runs across anterior wrist deep to tendons of flexor digitorum profundus (FDP)

Anastomoses with palmar carpal branch of radial artery to form palmar carpal arch

Dorsal carpal branch

Arises proximal to pisiform

Crosses dorsal to wrist

Anastomoses with dorsal carpal branch of radial artery to form dorsal carpal arch

Superficial branch of ulnar artery in hand-continues into palm as superficial palmar arch

Deep (palmar) branch of ulnar artery in the hand

Anastomoses with radial artery

Forms deep palmar arch

Venous Drainage of Hand and Forearm

Veins of hand

Superficial and deep palmar venous arches

Dorsal venous network (arch)

Both drain to cephalic and basilic veins

Superficial veins of forearm

Basilic vein ascends posteromedially on forearm

Cephalic vein ascends on lateral border of forearm

Median cubital vein connects cephalic and basilic over cubital fossa

Deep veins of forearm

Paired radial and ulnar veins and interosseus veins accompany arteries of same name

All communicate with superficial veins and median cubital vein

Venous Drainage of Arm

Superficial veins (drain into axillary vein)

Cephalic vein

On anterolateral surface

Enters groove between deltoid and pectoralis major (deltopectoral groove)

Then deltopectoral triangle

Empties into termination of axillary vein

Basilic vein

Medial side, inferior arm

Pierces deep fascia at junction of inferior and middle third of arm

Runs superiorly to axillary vein
