UPPER LIMB
TRUE OR FALSE
About the fracture of the clavicle
1. Commonly occurs by a direct force resulting from violent impacts to the outstretched hand
during a fall
2. Fracture is often of the greenstick type
3. Often occurs at the junction of its middle and lateral thirds
4. The clavicles of children are more frequently fractured than that of adults
5. After fracture of the clavicle, the sternocleidomastoid muscles elevates the medial
fragment of the bone
The four bones in the proximal row of the carpus are the
6. Trapezium
7. Capitates
8. Pisiform
9. Hamate
10. Lunate
About the brachial plexus
11. It is formed by the union of the ventral rami of C5 through C8 nerves
12. It is the major nerve network supplying the upper limbs
13. The roots of the brachial plexus pass through the gap between the anterior and middle
scalene muscles
14. The roots unite in the inferior part of the neck to form the trunks
15. The anterior division of the inferior trunk continues as the medial cord
Branches of the posterior cord includes
16. Upper subscapular nerve
17. Thoracodorsal nerve
18. Lower subscapular nerve
19. Axillary nerve
20. Radial nerve
About Klumpke’s paralysis
21. Site of injury is the lower trunk of the brachial plexus
22. Caused by undue separation of the head from the shoulder
23. Nerve roots involved are mainly T1 and partly C8
24. Deformity is known as “Policeman’s tip hand”
25. Intrinsic muscles of the hand are paralyzed
, ANATOMY: UPPER LIMB, THORAX AND LOWER LIMB MCQ COMPILATION
The Thoracodorsal nerve
26. Supplies the latissimus dorsi
27. Has root values C6, C7 and C8
28. Passes superiorly along the posterior wall of the axilla
29. Is vulnerable to injury during operations on scapular lymph nodes
30. Is usually injured during fracture of the proximal end of the Humerus
Concerning axillary lymph nodes
31. They enlarge and become tender when infections of the upper limbs occur
32. The humeral groups of nodes are the first one to be involved in lymphadenitis
33. The long thoracic nerve is in danger of injury during axillary lymph node dissection
34. Infections in the superior part of the abdomen can produce enlargement of axillary lymph
nodes
35. The central group is situated deep to the pectoralis minor
Concerning the boundaries of the axilla
36. The anterior wall is formed by the serratus anterior wall
37. The posterior wall is formed by the Clevipectoral fascia
38. The lateral wall is formed by the superior edge of the subscapularis
39. The apex is formed by the thoracic wall
40. The medial wall is formed by the intertubercular groove
Content of the axilla includes
41. Lymphatic vessels
42. The Thoracoacromial artery
43. The axillary sheath
44. The pectoral group of axillary lymph nodes
45. Some variable amount of fat
Concerning the brachial artery
46. It provides the main arterial supply to the forearm
47. It begins at the inferior border of the teres major muscles
48. It is superficial and palpable throughout its course
49. It accompanies the radial nerve through the radial grove
50. The best place to compress the brachial artery is at the radial styloid
Concerning the sternoclavicular joint
51. It is a saddle type of synovial joint
52. It is divided into two compartments by an articular disc
53. Is the only articulation between the upper limb and the axial skeleton
54. Is not palpable
55. The lateral end of the clavicle articulates with the manubrium at the sternal angle
Concerning the Glenohumeral joint
56. The shallow humeral head articulates with the round glenoid cavity of the scapula
57. It has more freedom of movement than any other join in the body
