Across
- 2. Fracture of the humerus usually occurs here. (Hint: posterior circumflex artery and axillary nerve is endangered)
- 7. This artery runs along the radial groove on the shaft of the humerus.
- 9. This nerve supplies latissimus dorsi and is a branch of the posterior cord of the brachial plexus (infraclavicular branch)
- 11. This pronator muscle is located in the deep layer of the anterior compartment of the forearm.
- 12. Direction that the humerus is most likely to dislocate.
- 13. The muscle most directly responsible for elevating a fractured clavicle.
- 15. Injury to this nerve results in wrist drop.
- 16. Support for the glenohumeral joint is mainly provided by these.
- 17. Bone that lies on palmar surface of triquetrum.
- 19. Sensation over the inferior portion of the deltoid is supplied by this nerve.
- 20. “Tennis elbow” affects this epicondyle.
- 21. Number of tendons passing through carpal tunnel.
Down
- 1. Muscle in the superficial layer of the anterior compartment of the forearm which is supplied by the ulnar nerve.
- 3. Both the dorsal and palmar interossei muscles are supplied by this nerve. (Hint: dorsal interossei muscle wasting can occur when a lung carcinoma / Pancoast tumour compresses the T1 nerve root)
- 4. Dermatome located over middle finger.
- 5. This nerve supplies the entire palmar surface. (Hint: its palmar cutaneous branch arises proximal to the flexor retinaculum and hence is not affect by carpal tunnel syndrome)
- 6. First long bone to ossify, but last to fuse.
- 8. Fracture to surgical neck of humerus places this artery at risk of damage.
- 10. Winging of scapula is caused by damage to this nerve. (Hint: supplies serratus anterior)
- 13. ‘Waiter’s tip position’ often results from damage to this part of the brachial plexus. (Hint: injuries occur from increasing the angle between the neck and shoulder – e.g. thrown from a horse and landing on shoulder)
- 14. This nerve supplies biceps brachii, coracobrachialis and brachialis.
- 18. Structure that is mainly comprised of fat, is the major passage for things entering the arm, and is bounded medially by the pectoralis major and minor.
