Upper Limb Flashcards
From arch of aorta to the lateral border of 1st rib
Subclavian artery
Branches of subclavian artery
Internal thoracic artery
Vertebral artery
Thyrocervical trunk
Continuous with superior epigastric artery which anastomoses with inferior epigastric artery (artery branch of external iliac artery
- provides collateral circulation if the abdominal aorta is blocked
Internal thoracic artery
3 branches of thyrocervical trunk
Suprascapular artery
Transverse cervical artery
Inferior thyroid artery
Collateral circulation around the shoulder
Surpascapular artery
Transverse cervical artery
Continuation of subclavian artery, extends from the lateral border of 1st rib to the inferior border of the TERES major muscle.
The tendon of Pectoralis minor muscles crosses the axillary artery anteriorly
Axillary artery
May be damaged by midshaft fracture of the humerus along with the radial nerve as they travel together in the posterior aspect of the humerus in the radial groove
Deep branchial artery (brachial artery)
Posterior to the tendons of flexor digitorum superficialis & profundus
Deep laceration at the metacarpal-carpal joint that cuts the deep palmar arch also compromises FLEXION of fingers
Deep palmar arch
Branches of Axillary artery
Thoracoacromial artery
Lateral thoracic artery
Anterior humeral circumflex artery
Posterior humeral circumflex artery
Subscapular artery
Branches of brachial artery
Deep brachial artery
Radial artery
Ulnar artery
Commencement: Arch of aorta
Termination: Lateral border of 1st rib
Subclavian artery
Commencement: Lateral border of 1st rib
Termination: Inferior border of teres major
Axillary artery
Commencement: lateral border of the teres major
Termination: cubical fossa
Branchial artery
COLLATERAL CIRCULATION
Around the shoulder

COLLATERAL CIRCULATION
Around the elbow
Superior ulnar collateral artery
- anastomoses with posterior ulnar recurrent artery
Inferior ulnar collateral artery
- anastomoses with anterior ulnar recurrent artery
Middle collateral artery
- anastomoses with interosseous recurrent artery
Radial collateral artery
- anastomoses with radial recurrent artery
