Study Notes
Upper Limb Vasculature
- Right subclavian artery supplies the entire upper limb
- Both right and left subclavian arteries have the same course, going under the clavicle and into the axilla
Axillary Artery
- Divided into 3 parts based on its position relative to the pectoralis minor muscle
- 1st part: lies before the muscle, gives off the Superior Thoracic artery
- 2nd part: covered by the muscle anteriorly, gives off 2 branches:
- Thoraco-acromial artery
- Lateral thoracic artery
- 3rd part: lies after the muscle, gives off 3 branches:
- Subscapular artery
- Anterior circumflex humeral artery
- Posterior circumflex humeral artery (passes through the quadrangular space and runs with the axillary nerve)
Brachial Artery
- Starts at the lower border of the teres major or pectoralis major muscle
- Runs down the arm, giving off 2 main branches:
- Deep brachial (profunda brachii) artery
- Muscular branches (2-5)
Arteries of the Forearm
- Brachial artery ends in the distal part of the cubital fossa, dividing into:
- Ulnar artery (larger of the 2 terminal branches)
- Radial artery (smaller of the 2 terminal branches)
- Ulnar artery:
- Lies under the flexor carpi ulnaris and accompanies the ulnar nerve
- Supplies the elbow, muscles of the anterior compartment on the medial side, and the deep muscles of the anterior compartment of the forearm
- Radial artery:
- Descends on the lateral side of the forearm under the cover of the brachioradialis muscle
- Supplies the elbow, muscles of the anterior compartment on the lateral side, and muscles on the lateral side of the posterior compartment
Arteries of the Hand
- Radial artery is the major source of blood supply for the dorsal surface of the hand
- Branches of the radial artery form:
- Dorsal carpal (arterial) arch
- Dorsal metacarpal arteries
- Dorsal digital arteries
- Other branches of the radial artery join with the terminal branches of the ulnar artery to form:
- Superficial palmar branch of the ulnar artery
- Deep palmar branch of the ulnar artery and deep branch of the ulnar nerve
Surface Anatomy of Upper Limb and Venous Return of Upper Extremity
- Venous system of the upper limb drains deoxygenated blood from the hand, forearm, and arm
- Anatomically divided into:
- Superficial veins (run within superficial fascia of the upper limb)
- Deep veins (run with arteries and usually take the name of the region)
Upper Limb Area of Transition
- Axilla: a 4-sided pyramidal space situated between the upper part of the arm and the chest wall
- Cubital fossa: a triangular impression in front of the elbow joint bounded by the brachioradialis and pronator
- Carpal tunnel: 9 tendons and 1 nerve
Contents of Axilla
- Axillary artery and its branches
- Axillary vein and its tributaries
- Infraclavicular part of the brachial plexus
- Axillary Lymph nodes: receives lymph from the upper limb and chest wall
Test your knowledge of the right subclavian artery and the course of the axillary artery as it divides into three parts. Learn about the transitional areas and blood supply of the upper extremity.
