Anatomy: Musculoskeletal 4

Aim

Become familiar with the anatomy of the forearm and hand.

Outcomes

1. Locate the carpal bones.

2. Locate the position of the flexor retinaculum and its bony attachments.

3. Identify the nature and contents of the carpal tunnel

4. Identify the muscles that move the thumb and the arrangement of the flexor tendons for a typical finger.

5. Identify the muscle groups involved in flexion at the wrist and fingers and list the segmental spinal nerve roots responsible for each movement

6. Locate the course of the median nerve and palmar arterial arches in the forearm/hand.

7. Locate the tendons, nerves and pulses on the volar aspect of the wrist.

8. Identify the muscle groups involved in extension of the wrist and fingers.

9. Demonstrate and test extension at the wrist, and list the spinal segmental root values involved in these movements.

10. Identify the boundaries and contents of the "anatomical snuff box".

11. Demonstrate the movements of the thumb and fingers.

12. Demonstrate the territories of cutaneous sensation in the ha

?

1. which is false of shaft and distal radius

  • head articulates with scaphoid and hamate carpal bones
  • styloid process on lateral surface of the bone
  • dorsal tubercle for an extensor of the thumb
  • interosseous border provides attachment for the interosseous membrane
  • ulna notch for articulation with ulna

Other questions in this quiz

2. which is false of the distal/shaft of ulnar

  • radius articulates with ulna in three places
  • styloid process projects distally and articulates with the ulna notch
  • superior surface of olecronon provides attachment for triceps
  • interosseous boder runs on lateral surface
  • head is rounded and covered in articular cartiage

3. which is true of the foream extensors

  • superficial extensors all originate from the medial epicondyle
  • three layers superficial, intermediate and deep
  • supination
  • flexion of fingers
  • movement of elbow joint

4. extensor muscles are supplied by the radial nerve C6,7,8 damage could result in wrist drop

  • True
  • False

5. which is false of the forearm extensors

  • extensor carpi ulnaris extends and adducts the wrist
  • deep layer except supinator all arise from interosseous mebrane
  • brachicoradialis extends and abducts the wrist
  • supinator arises from lateral epicondyle
  • extensor carpi radialis extends and abducts the wrist
