Q

Which band of connective tissue forms the “roof” of the carpal tunnel?

A

Flexor Retinaculum

21
Q

What bones are the medial attachments sites for the “roof” of the carpal tunnel?
What is the “roof” called?

A

Hook of the hamate and pisiform

Flexor retinaculum

22
Q

What forms the Tunnel of Guyon?

A

The pisiform and hook of hamate

23
Q

What 2 structures pass through theTtunnel of Guyon?

A

Ulnar nerve and Ulnar artery

24
Q

How do you palpate the hook of hamate?

A

Accessible on the hand’s dorsal surface where the bases of the fourth and fifth metacarpals merge. Hook is often tender when palpated.

25
Q

List your pneumonic to remember the 8 carpals

Bonus for Tunnel of Guyon and Flexor reticulum

A

1) (For the proximal)
- Scaphoid and Lunate (sail to the moon) to try (Triquetrum) position (Pisiform)

2) (For distal, focus on fingers)
- Index hangs with Thumb (Trapezium) to avoid being trapped with the middle (Trapezoid) because Ring Queen decapitates hamate who has a hook (Capitate, Hamate)

Bonus) Hook of Hamate try positions (pisiform) to form the sea Tunnel of Guyon where Ulnar nerve and artery shall pass. To sail the river, Scaphoid joins with the index-thumb (trapezium)

26
Q

Which muscles primarily act on the elbow?

A
  • Brachialis

- Brachioradialis

27
Q

Which muscle group moves the wrist and/or fingers?

A
  • Flexors of wrist and fingers
  • Abductors of wrist
  • Extensors of wrist and fingers
  • Adduction of wrist
28
Q

What muscles create pivoting action between the radius and ulna?

A

Pronator teres
Supinator
Pronator quadratus

29
Q

Where are the flexor and where do they originate from mostly?

A

Anterior, medial epicondyle

30
Q

Where are the extensors and where do they originate mostly?

A

Posterior, lateral epicondyle

31
Q

What type of joint is the distal radioulnar joint?

A

Gliding

32
Q

What type of joint is the radiocarpal joint

A

Ellipsoid (flex/ex, ulnar/radial dev.)

33
Q

What type of joint are the CMC of 2-5?

What type of joint are the CMC of 1st?

A

Gliding

Saddle

34
Q

What type of joint are the MCP (knuckles)?

A

ellipsoid

35
Q

What type of joint are the PIP and DIP (thumb only has PIP)?

A

Hinge

4 dist carpals
5 MC
14 phalanges
37

39
Q

What’s another name for achille’s tendon?

A

calcaneal tendon

40
Q

Which two carpals tend to get broken?

A

Scaphoid and lunate (scaphoid has tubercle)

41
