Distal ulna and radius

Question 1

Distal ulna

Answer 1

Bone tapers from top (smaller at base)
Head at distal site
Ulnar styloid process

Question 2

Ulna styloid process function

Answer 2

Collateral wrist ligaments attach

Question 3

Distal radius

Answer 3

Bone larger at distal end

Ariculates with carpals

Question 4

Lateral radius

Answer 4

Styloid process - collateral ligaments attach

Question 5

Medial radius

Answer 5

Ulna notch for ulna head to articulate

Question 6

Posterior distal radius

Answer 6

Dorsal tubercle - allow extensor pollucis longus to change directions of pull

Question 7

Carpal bone organisation

Answer 7

2 rows of 4
Proximal - articulate with radius
Distal - articulate with metacarpals

Question 8

metacarpal parts

Answer 8

head
body
base

Question 9

hand bones

Answer 9

carpals (base)
metacarpals
phalanges (3 per finger apart from thumb)

Question 10

Joints of the hand

Answer 10

metacarphalangeal 
interphalangeal (distal and proximal)

Question 11

Proximal carpal bones

Answer 11

Scaphoid
Lunate
Triquetrum
Pisiform

Straight line to pinky

Question 12

Distal carpal bones

Answer 12

Hamate
Capitate
Trapezoid
Trapezium

Here comes the thumb

Question 13

carpal tunnel borders

Answer 13

roof: flexor retinaculum
Lateral: scaphoid and trapezium
Medial: Hamate and pisiform

Question 14

Contents of carpal tunnel

Answer 14

flexor tendons - 
flexor digitorum superficialis and profundus (superficialis on top)
flexor pollucis longus 
Median nerve (most superficial)

(NOT ULNAR NERVE)

Question 15

Rhyme for carpals

Answer 15

Triquetral = proxiMAL
Trapezium = under the thumb

Question 16

How does ulnar nerve enter the hand?

Answer 16

Guyons canal

Question 17

Distal radioulnar joint

Answer 17

Triangular ligament unites (fibrocartilagenous)
Ulna notch on radius and ulna head
Radius takes hand with it

Question 18

Function of triangle ligament

Answer 18

Separates radioulnar joint from wrist joint

Loose around superior to allow radius to move around

Question 19

Where is guyons canal?

Answer 19

Near pisiform (ulnar border)
hook of hamate (radial border)
