22
Q

The wrist joint is medically known as?

What type of joint is this?

A

Synovial ellipsoid joint

23
Q

What is the difference between the condyloid and ellipsoid joint?

A

Condyloid is convex an ellipsoid is convex

24
Q

State the bones which form the proximal and distal carpal bones.

A

The proximal row of carpal bones (moving from radial to ulnar) are the scaphoid, lunate, triquetrum, and pisiform, while the distal row of carpal bones (also from radial to ulnar) comprises the trapezium, trapezoid, capitate, and hamate.

25
Q

How many structures pass through the carpal tunnel?

Name them.

A 
10
The tendons of flexor digitorum superficialis (4)
The tendons of flexor digitorum profundus (4)
Median nerve (1)

tenosynovitis

27
Q

Which 4 carpals make up the boundaries of the carpal tunnel?

A

hamate, capitate, trapezoid and trapezium

28
Q

Which ligament contributes towards the formation of the roof of the carpal tunnel?

A

Transverse ligament

29
Q

Which nerve supplies Opponens Pollicis?

A

Median nerve

30
Q

Which arteries supply the hand?

A

deep palmar arch and superficial palmar arch

31
Q

Which veins drain the fingers?

A

extensor pollicis longus

33
Q

Which ligament helps to stabilize the radio carpal joint?

A

Doral radio carpal ligament

34
Q

The radio carpal ligament runs from the dorsal surface of the distal radius to the ?

A

Triquetrum

35
Q

Which two tendons contribute towards the formation of the anatomical snuff box?

A

abductor pollicis longus and extensor pollicis brevis

36
Q

A

Collateral ligament metcarpophalangeal

39
Q

Which ligament stabilizes the metacarpal phalangeal junction?

A

Transverse metacarpal ligament

40
Q

Which ligaments prevents displacement of the metatarsal bones?
What is the articulation between the metacarpal joints called? What type of joint is this?

A

Dorsal and palmar metacarpal ligaments
Intermetacarpal joints
Synovial plane joint

41
Q

Which ligament extends from the radius to the lunate?

Extension 70 to 90
Ulnar deviation 30 to 45
Radial Deviation 15

44
Q

Why is radial deviation restricted in comparison to to ulnar deviation?

A

The extension of the radial styloid process generates a restrictive barrier.

Anterior and posterior glide
Medial and lateral shear

46
Q

Which muscles perform ulnar deviation?
