VESSELS OF UPPER LIMB
SUBCLAVIAN ARTERY
SUBCLAVIAN ARTERY• Extent: origin to outer border of 1st rib
• Parts: 3 with reference to scalenus anterior muscle
• Branches– 1st part: Vertebral, Internal thoracic & Thyrocervial
trunk
– 2nd part: Costocervical trunk
– 3rd part: Dorsal scapular artery
Axillary artery
Axillary artery
• Extent: 1st rib to teres major
• Parts: 3; with reference to
pectoralis minor
• Branches– 1st part: Superior thoracic
– 2nd part: thoracoacromian &
lat thoracic
– 3rd part: subscapular, ant
circumflex & post circumflex
• Extent: teres major to head of radius
• Branches:– Profonda brachii– Superior ulnar collateral– Inferior ulnar collateral– Nutrient to humerus– Radial– Ulnar
Brachial artery
Radial artery
• Extent: origin to between the heads of adductor pollicis
• Continuation: deep palmar arch
Radial artery: branches• Forearm– Radial recurrent artery– Palmar carpal branch– Superficial palmar branch
• Wrist– Dorsal carpal branch– First dorsal metacarpal
artery• Hand– Princeps pollicis– Radialis indicis– Deep palmer arch
Ulnar artery• Larger of 2 terminal
branches of brachial
artery
• Extent: origin to
transverse carpal
ligament
• Continuation:
superficial palmer
arch
Ulnar artery: branches• Anterior ulnar recurrent
• posterior ulnar recurrent
• common interosseous
• muscular artery
• Palmer carpal
• Dorsal carpal
• Deep palmer
• Superficial palmer arch
Palmer arches• Deep
– Radial artery + deep branch of ulnar
– At base of metacarpels & interossei
– covered by oblique head of the
adductor pollicis, the flexor tendons
of fingers and lumbricals
– Br: Palmer metacarpel arteries
• Superficial– Ulnar + sup br of radial
– At distal border of extended thumb
– Br: 3 common palmer digital
branches
veins
