Wrist + Hand Muscles Flashcards
1
Q
Flexor carpi radialis
A
action = wrist flexion, radial deviation of hand innervation = median nerve
2
Q
Palmaris longus
A
action = wrist flexion innervation = median nerve
3
Q
Flexor carpi ulnaris
A
action = wrist flexion, ulnar deviation of hand innervation = ulnar nerve
4
Q
Flexor digitorum superficialis
A
action = flexion of wrist, flexion of middle & proximal phalanges 2-5 innervation = median nerve
5
Q
Deep Flexors of Wrist (2)
A
- Flexor pollicis longus
2. Flexor digitorum profundus (FDP)
6
Q
Flexor pollicis longus
A
action = flexion of thumb innervation = median nerve
7
Q
Flexor digitorum profundus (FDP)
A
action = wrist flexion, flexion of distal phalanges 2-5 innervation = palmar interosseous nerve
8
Q
Superficial Extensors of Wrist (5)
A
- Extensor carpi radialis longis
- Extensor carpi radialis brevis
- Extensor digitorum
- Extensor digiti minimi
- Extensor carpi ulnaris
9
Q
Extensor carpi radialis longis
A
action = extension + abduction of wrist innervation = radial nerve
10
Q
Extensor carpi radialis brevis
A
action = extension + abduction of wrist innervation = radial nerve
11
Q
Extensor digitorum
A
action = wrist extension, extension of digits 2-5 innervation = deep radial nerve
12
Q
Extensor digiti minimi
A
action = wrist extension, digit 5 extension innervation = deep radial nerve
13
Q
Extensor carpi ulnaris
A
action = extension + adduction of wrist innervation = deep radial nerve
14
Q
Deep Extensors of Wrist (4)
A
- Abductor pollicis longus (APL)
- Extensor pollicis longus (EPL)
- Extensor pollicis brevis (EPB)
- Extensor Indicis
15
Q
Abductor pollicis longus (APL)
A
action = thumb + wrist abduction innervation = deep radial nerve
