1. Describe the lymphatic circulation of the mammary gland Describe the characteristic features of Erb-Duchenne palsy and Klumpke’s paralysis Describe the arterial supply of the hand and layers of the palmar region Describe the cutaneous innervation of the upper limb Describe the rotator cuff muscles and the avulsion fracture of the greater tubercle Describe the scapular arterial anastomosis and its clinical importance Describe the pathogenesis of claw hand, ape hand, hand of benediction and wrist drop Describe the borders and content of the cubital fossa, medial and lateral axillary spaces Describe the carpal tunnel syndrome and the Dupuytren’ s contracture Describe the anatomical snuff box – borders, content Describe the spinal chord levels associated with upper limb movements and reflexes

2. Describe the lymphatic circulation of the mammary gland Mammary gland, pectoreal (anterior lymph node), central, apical nodes To sublcavian trunk, to right subclavian trunk, jugular vein (on right; thoracic duct on left)

3. Describe the characteristic features of Erb-Duchenne palsy and Klumpke’s paralysis Clinical correlates; pages 38-42 in lab book Erb is waiter’s tip –No abduction, lateral rotation, arm flexors Klumpke’s is claw HAND

4. Describe the arterial supply of the hand and layers of the palmar region Deep (radial a.) and superficial (ulnar a.) palmar arches –Branches of the radial/ulnar arteries Radial is more the deep side –supplies index, thumb as well SUper DR –Superficial ulnar –Deep Radial (interossei, lumbricals, deep muscles) Superficial branch splits into common digital arteries, which go up to become the proper digital arteries

5. Describe the cutaneous innervation of the upper limb Cutaneous innervation map

6. Describe the rotator cuff muscles and the avulsion fracture of the greater tubercle Subscapularis goes to the lesser tubercle –Other 3 go to the greater tubercle –Subscapularis would not be affected and would medially rotate your arm; lateral rotators lost Not attached to lesser tubercle –Originates from the subscapular fossa Medial rotators of arm –2 Majors and a Sexy Lady Pec/teres major, subscapularis, latissimus dorsi

7. Describe the scapular arterial anastomosis and its clinical importance Transverse cervical (dorsal scapular artery) –From subclavian Suprascapular artery –From subclavian Circumflex scapular artery –From the subscapular artery Importance= if one of the arteries is blocked, there will still be a blood supply to the muscles in the area

8. Describe the borders and content of the cubital fossa, medial and lateral axillary spaces Tendon of biceps, brachial artery, median nerve Pronator teres on medial side, brachioradialis on lateral side Triangular Space (t. minor over t. major) –Circumflex scapular artery Quadrangular Space (long head of biceps medially, humorous lat, t. minor superior, t. major inferior) –Axillary nerve, posterior circumflex artery

9. Describe the carpal tunnel syndrome and the Dupuytren’ s contracture 3 benediction –Dupuytren’s (palmar aponeurosis) Ulnar claw, median (Ape hand) median nerve; dig. Superficialis, dig. Profundus, flexor pollicis longus –10 things through the carpal tunnel

10. Describe the anatomical snuff box – borders, content Extensor pollicis longus (medial border), extensor pollicis brevis (lateral), abductor pollicis longus (lateral) Floor is scaphoid and trapezium Radial artery, nerve and cephalic vein are in there

11. Describe the spinal chord levels associated with upper limb movements and reflexes C5 (for biceps) tap the cubital fossa C6 (for brachioradialis) tap radial nerve –Right before the distal portion of the radius C7 (for triceps) tap right above elbow joint C5-C6 is shoulder C5 is abduction (up), C6 is flexing, C7 is extension of arm/forearm, C8 is wrist, T1 is ab/adduction of fingers
