Question 4

Give the borders of the carpal tunnel

Answer 4

Deep carpal arch- laterally the scaphoid and trapezium, medially the hook of hamate and pisiform

• 4 tendons of flexor digitorum profundus
• 4 tendons of flexor digitorum superficialis
• Median nerve

Question 6

Give the borders of the anatomical snuff box

Answer 6

Ulnar border- tendon of extensor pollicis longus

Radial border- tendons of extensor pollicis brevis and adductor pollicis longus

Proximal border- styloid process of the radius

Floor- scaphoid and trapezium

Roof- skin

Question 7

Give the contents of the anatomical snuff box

Answer 7

• radial artery
• superficial branch of radial nerve
• cephalic vein

Question 8

Give the borders of the femoral triangle

Answer 8

Superior border- inguinal ligament

Lateral border- medial border of sartorius

Medial border- medial border of the adductor longus

Floor- pectineus, iliopsoas, adductor longus

Roof- skin and fascia

Question 9

Give the contents of the femoral triangle

Answer 9
