Artery of upper limbsArtery Explanation Branches Axillary Continuation of subclavian art.

Origin : outer border of 1st ribEnds : lower border of teres major muscle

Continues as brachial art. Pectoralis minor divides it into 3 parts:

1st: proximal 2nd : deep 3rd : distal

Major relations : cords of brachial plexus, axillary vein

1st part (1 branch) Superior thoracic art.

2nd part( 2 branches) Thoracoacromial art

( acromiothoracic) Lateral thoracic art (main art

to breast) 3rd part (3 branches)

Subscapular art (largest br.) Anterior circumflex humeral

art Posterior circumflex humeral

artBrachial Continuation of axillary ar.

Origin : lower border of teres major muscleEnds : below elbow, at level of the neck of radius

Divides into radial and ulnar arteries at medial aspects of humerus

Supplies flexor muscles of the arm and anastomosis around elbow

Cubital fossa ( BP measurements)*lateral to medial T (tendon of biceps) A (artery –brachial) N (nerve- median)

Profunda brachii art. Muscular branche art. Superior ulnar collateral art. Inferior ulnar collateral art. Nutrient art of humerus Radial and ulnar (terminal

branches)

Radial Smaller terminal br. of brachial art. Origin: in the cubital fossa at the level neck

of radiusEnds : Continues into the hand at anatomical snuff box, Re-enters the palm by piercing 1st interosseous muscle

Pulse:- Felt at lateral part of wrist, between lower end of radius and tendon of flexor carpi radialis

Muscular branches Radial recurrent art. Parmal carpal art. Princeps pollicis art. Radialis incidis art. Supercial palmar art.

Ulnar Larger terminal br. of brachial art. Origin : In the cubital fossa at the level of the

neck of the radiusEnds : Continues into the hand forming the superficial palmar arch

Muscular branches Anterior ulnar recurrent art. Posterior ulnar recurrent art. Common interosseous art. Palmar and dorsal carpal art. Superficial palmar art.

Superior palmar arch Deep palmar arch Beneath palmar aponeurosis (deep fascia) The level of distal border of abducted and

extended thumb Anastomosis between

Ulnar artery (main trunk) Radial artery (superficial branch)

Branches Four digital branches

Anastomosis between Radial artery (main trunk) Ulnar artery ( deep branch)

Branches Three palmar metacarpal arteries. Perforating branches
