Flashcards in Anatomy of the Wrist and Forearm Deck (25):
1

Describe the route that the radial nerve takes?

Travels posterior to the humerous and travels inside the radial grove alongside the profunda brachii artery (branch of the brachial artery), it then passes lateral to the lateral epicondyle

2

Which part of the humerous articulates with the radius head?

Capitulem

3

Where is the coracoid fossa located and what is its significance during flexion of the elbow?

Coranoid fossa lies superior to the ulnar bone and during flexion the coranoid process of the ulnar bone sits within this fossa

4

What part of the humerous articulates with the ulnar head?

Trochlear

5

Where does the tendon of brachialis muscle attach onto inferiorly?

Ulnar

6

What holds the radius against the capitulem?

Ring of annular ligament

7

Where does the tendon of biceps brachii muscle attach onto inferiorly?

Radius

8

What lies in-between the radius and ulnar?

Interroussus membrane

9

What muscles bring about supernation?

Supernator
Biceps brachii

10

What muscles bring about pronation?

Pronator teres
Pronator quadratus

11

Name the 4 distal carpal bones from medial to lateral?

Hamate
Capitulate
Trapezoid
Trapezium

12

Name the 4 proximal carpal bones from medial to lateral?

Pisiform
Triquetrium
Lunate
Scaphoid

13

Name all of the superficial muscles of the anterior compartment of the forearm?

Pronator teres
Flexor carpi radialis
Palmaris longus (may be absent)
Flexor digitorum superficialis
Flexor carpi ulnaris

14

What is the nerve innervation of the superficial muscles of the anterior compartment of the forearm? Which muscle is an exception to this and what is its nerve supply?

Median nerve
Flexor carpi ulnaris
Ulnar nerve

15

Name all of the deep muscles of the anterior compartment of the forearm?

Pronator quadratus
Flexor digitorum profundus
Flexor pollicis longus

16

Which muscle of the forearm receives bi-nerve innervation, and what two nerves supply this?

Flexor digitorum profundus (deep/anterior compartment)
Ulnar and median nerve

17

Where do all of the superficial muscles of the anterior compartment attach onto superiorly?

Medial epicondyle

18

Name all of the superficial muscles of the posterior compartment of the forearm?

Brachioradialis
Extensor carpi radialis longus
Extensor carpi radialis brevis
Extensor digitorum
Extensor digiti minimi
Extensor carpi ulnaris

19

Name all of the deep muscles of the posterior compartment of the forearm?

Supernator (wank muscle)
Abductor pollicus longus
Extensor pollicus brevis
Extensor Pollicus Longus
Extensor indicus

20

What is the nerve supply on both of the posterior compartments of the forearm?

Radial nerve

21

What fracture concerning the wrist is likely to occur in older people?

Colles fracture (distal radius)

22

What fracture concerning the wrist is likely to occur in younger people?

Scaphoid fracture - this can lead to avascular necrosis

23

Name the five P's associated with compartment syndrome?

Pain
Paraesthesia
Pallor
Paralysis
Pulselessness

24

What is the superior attachment of the extensor compartment of the forearm muscles?

Lateral epicondyle

25

Name the branch from the median nerve which supplies the deep flexor compartment of the forearm?

Anterior interrousus nerve
