Flashcards in Wrist primary structures Deck (13):
1

What structures form the anatomic snuffbox?

APL
EPL
EPB

2

This structure is close to the deep surface of the flexor retinaculum. Median nerve passes through

carpal tunnel

3

This is the only major ligament on the dorsal aspect of the wrist

dorsal radiocarpal ligament

4

This retinaculum prevents tendons from bowstringing as the wrist is extended

extensor retinaculum

5

This structure crosses the palmar aspect of the wrist, forming part of the carpal tunnel. Prevents bowstringing of tendons during wrist flexion

flexor retinaculum

6

The flexor retinaculum serves as the attachment point for these muscles

thenar
hypothenar

7

function of the interosseous membrane

stabilizer against axial forces applied at the wrist

8

This ligament limits ulnar deviation and becomes taut when the wrist is in extremes of extension and flexion.

radiocarpal ligament

9

TFCC

cartilaginous disc that sits between the ulna, lunate, and triquetrum

10

Function of TFCC

- provides stability to wrist jt
- connects radius and ulna together
- allows force distribution through wrist

11

Tunnel of Guyon located between

- hook of hamate
- pisiform
- palmar carpal ligament
- flexor retinaculum

12

What passes through the tunnel of Guyon?

- ulnar nerve
- ulnar artery

13

Compression of tunnel of Guyon may result in

ulnar tunnel syndrome
