Study Notes
Veins of the Forelimb
- The cephalic vein is important for venipuncture and catheter placement and drains into the external jugular vein, then to the cranial vena cava, and finally to the right atrium of the heart.
- The medial cubital vein links the cephalic vein to the brachial vein for deep vein drainage.
Deep Veins
- Deep veins are satellites to arteries of the same name.
Collateral Circulation
- Collateral circulation involves multiple arterial branches supplying one given area or muscle.
- If one artery is blocked, collateral blood flow prevents necrosis in the servicing region.
Arteries of the Forelimb
- The main arteries of the forelimb include the subclavian artery, axillary artery, brachial artery, and median artery.
- The axillary artery has four branches: external thoracic artery, lateral thoracic artery, subscapular artery, and cranial circumflex humeral artery.
Branches of the Axillary Artery
- The external thoracic artery supplies the superficial pectoral muscle.
- The lateral thoracic artery supplies the axillary lymph node, deep pectoral muscle, latissimus dorsi muscle, and cutaneous trunci muscle.
- The subscapular artery supplies the subscapularis muscles, part of the teres major muscle, and the scapula, and has two branches: thoracodorsal and caudal circumflex humeral.
- The thoracodorsal artery branch supplies the teres major muscle and latissimus dorsi muscle.
- The caudal circumflex humeral artery branch courses laterally between the humerus and teres major muscle, supplying the shoulder joint.
- The cranial circumflex humeral artery supplies the biceps brachii muscle and the shoulder joint.
Branches of the Brachial Artery
- The brachial artery has six branches: deep brachial artery, bicipital artery, collateral ulnar artery, superficial brachial artery, transverse cubital artery, and common interosseous artery.
- The deep brachial artery supplies the triceps muscle group.
- The bicipital artery supplies the biceps brachii muscle distally.
- The collateral ulnar artery is a large branch that runs deep to the medial head of the triceps muscle to the caudal elbow.
- The superficial brachial artery supplies the cranial surface and superficial brachium.
- The transverse cubital artery supplies the cranial elbow, diving deep into the elbow joint.
- The common interosseous artery is short and dives between the radius and ulna, having three branches that supply the antebrachium.
Median Artery
- The median artery is the principal blood supply to the manus (front paw), passing through the carpal canal.
