Study Notes
Bones of the Upper Limb
- Clavicle
- Scapula
- Humerus
- Radius
- Ulna
- Carpals: Scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate
- Metacarpals
- Phalanges: Proximal, middle, distal
Muscles of the Upper Limb
- Anterior Axioappendicular Muscles: Pectoralis major, pectoralis minor, subclavius, serratus anterior
- Posterior Axioappendicular & Scapulohumeral Muscles: Trapezius, latissimus dorsi, levator scapulae, rhomboid major & minor, deltoid, supraspinatus, infraspinatus, teres minor, teres major, subscapularis
- Anterior (Flexor) Compartment of the Arm: Biceps brachii, brachialis, coracobrachialis
- Posterior (Extensor) Compartment of the Arm: Triceps, anconeus
- Anterior (Flexor) Compartment of the Forearm: Pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus, pronator quadratus
- Posterior (Extensor) Compartment of the Forearm: Brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor digiti minimi, extensor carpi ulnaris, supinator, extensor indicis, abductor pollicis longus, extensor pollicis longus, extensor pollicis brevis
- Intrinsic Muscles of the Hand: Opponens pollicis, abductor pollicis brevis, flexor pollicis brevis, adductor pollicis, abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimi, lumbricals (I-IV), dorsal interossei (I-IV), palmar interossei (I-III)
Arterial Supply of the Upper Limb
-
Subclavian Artery: Extends from the arch of the aorta to the lateral border of the first rib.
- Branches: Internal thoracic artery, vertebral artery, thyrocervical trunk (suprascapular artery, transverse cervical artery, inferior thyroid artery)
-
Axillary Artery: Continuation of the subclavian artery, extends from the lateral border of the first rib to the inferior border of the teres major muscle.
- Branches: Superior thoracic artery, thoracoacromial artery (acromial, deltoid, pectoral, clavicular branches), lateral thoracic artery, anterior humeral circumflex artery, posterior humeral circumflex artery, subscapular artery (circumflex scapular artery, thoracodorsal artery)
-
Brachial Artery: Continuation of the axillary artery extending from the inferior border of the teres major muscle to the cubital fossa.
- Branches: Deep brachial artery (middle collateral, radial collateral arteries), superior ulnar collateral artery, inferior ulnar collateral artery, radial artery (recurrent radial artery, palmar carpal, dorsal carpal, superficial palmar, princeps pollicis, radialis indicis, deep palmar), ulnar artery (anterior ulnar recurrent, posterior ulnar recurrent, common interosseous (anterior & posterior interosseous), palmar carpal, dorsal carpal, deep palmar, superficial palmar)
Clinical Considerations of Upper Limb
- Subclavian Steal Syndrome: Retrograde flow in the vertebral artery due to ipsilateral subclavian artery stenosis.
- Surgical Ligatures: May be placed on the subclavian or axillary artery (between thyrocervical trunk and subscapular artery), or brachial artery (distal to the inferior ulnar collateral artery). Placement is avoided on the axillary artery between the subscapular artery and the deep brachial artery.
- Compression of the Axillary Artery: For controlling bleeding, the third part can be compressed against the humerus. More proximally, the first part can be compressed near its origin.
- Percutaneous Arterial Catheterization: Brachial artery is used if the femoral artery approach is unavailable. Preference is given to the left brachial artery.
- Blood Pressure Measurement: Brachial artery is used for blood pressure measurement.
