1. The superior lateral cutaneous nerve shares cord levels with the phrenic nerve and may refer pain from a perturbed liver.
a. False: referred pain from the liver reaches supraclavicular nerves
2. The cutaneous distribution of the supraclavicular nerves may be tested to asses injury to the axillary nerve.
a. False: axillary nerve gives rise to superior lateral cutaneous nerves
3. The intercostal brachial nerve is from the lateral branch intercostal nerve T5 and may refer pain from the heart.
a. False: lateral cutaneous branch of T2
4. The dorsal venous arch of the hand crosses superficial to branches of the superficial radial nerve.
a. True
5. The ulnar side of the dorsal venous arch gives rise to the cephalic vein and the radial side gives rise to the basilic vein.
a. False: ulnar side gives rise to basilic and radial side gives rise to cephalic
6. The superficial radial nerve extends to the finger tips of the radial three fingers.
a. False: extends on the dorsal 2 radial fingers but falls short of finger tips which are done by medial nerve
7. The dorsal branch of the ulnar nerve extends to the tips of the ulnar two fingers.
a. True
8. The median cubital vein crosses anterior to the bicipital aponeurosis.
a. True
9. Three muscles and two ligaments are known for attachments at the coracoid process.
a. True
10. The intertubercular sulcus and the transverse humeral ligament provide a osseofibrous tunnel that transmits the tendon of the long head of the biceps to within the glenohumeral joint capsule.
a. True
11. The suprascapular nerve and artery enter the supraspinous fossa at the scapular notch as the artery passes inferior, and the nerve passes superior, to the transverse scapular ligament.
a. False: Nerve passes inferior while artery passes superior to transverse scapular ligament
12. The suprascapular nerve and artery enter the infraspinous fossa by crossing the spinoglenoid notch.
a. True
13. If the axillary is ligated proximal to the subscapular artery there will be retrograde flow in the circumflex scapular artery.
a. True
14. The circumflex scapular artery enters the supraspinous fossa in the region of the triangular interval.
a. False: it enters the infraspinous fossa in the region of the triangular space
15. Abduction of the arm at the glenohumeral joint is initiated by the supraspinatus muscle and then continued by the deltoid muscle depending on the integrity of the suprascapular and axillary nerves respectively.
a. True
16. The acromial branch of the thoracoacromial trunk and the ascending branch of the profunda brachial artery participate in the shoulder anastomosis.
a. True
17. Passing the medial side of the levator scapulae is the superficial branch of the transverse cervical artery.
a. False: passes lateral to levator scapulae
18. Passing the medial side of the lavator scapulae is the dorsal scapular nerve.
a. True
19. Rhomboideus major and minor are primary protractors of the scapula.
a. True
