Elbow And Wrist Actions

Question 1

Elbow flexion

Main muscles

Answer 1

Biceps Brachii (Musculotaneus c5-c6)
Brachialis (musculotaneus)
Brachialradialis (radial nerve c5-c6)
Pronator teres (median nerve)

Question 2

Elbow extension

Answer 2

Triceps brachii

Radial nerve

Question 3

Forearm pronation

Answer 3

Pronator Quadrature (c7-c8 anterior antebrachial interosseous)
Pronator teres (c6-c7 median nerve)

Question 4

Forearm Supination

Answer 4

Supinator muscle (posterior antebrachial interossues nerve c6-c7)
Biceps Brachia (musculocutaneus nerve c5-c6)

Question 5

Wrist ulnar deviation

Answer 5

Extensor Carpi ulnaris (posterior antebrachial interosseus c7-c8)
Flexor carpi ulnaris (ulna nerve c7-t1)

Question 6

Wrist radial deviation

Answer 6

Abductor pollicis (posterior antebrachial interosseous nerve(c7-c8)
Extensor carpi radials longest (radial nerve c6-c7)
Extensor carpi radialis brevis (radial and brachial interosseous nerve)
Flexor carping radialis (median nerve c6-c7)

Question 7

Wrist flexion

Answer 7

Flexor carpi radialis (radial nerve c6-c7)
Flexor carpus ulnaris (posterior antebrachial interosseous c7-c8)
Palmers longus (median nerve c7-c8)

Question 8

Wrist Extension

Answer 8

Extensor carpi radialis brevis(c7-c8 Posterior antebrachial)
Extensor carpi radialis longus (radial nerve c6-c7)
Extensor carpi ulnaris (c7-c8 Posterior antebrachial)
Extensor digiti minimi (c7-c8 Posterior antebrachial)
Extensor indicis (Posterior antebrachial)
Extensor longus pollicis(Posterior antebrachial)
Extensor brevis pollicis (Posterior antebrachial c7c8)

Not sure why but extensor digitorum isn’t on the list but it is a big one so I am adding it
Posterior antebrachial interosseous c7-c8

Question 9

Inhibit/lengthen

Answer 9

Biceps Brachii
Wrist extensor
Wrist flexors
Brachialis

Question 10

Inverted row
Prone triceps extension w/ cobra
Standing cable press
Triceps extension progression

Question 11

Corrective program for
Wrist/elbow
Flexion

Answer 11

Stretch- Brachialis , biceps

Strengthen-triceps

Intergrate- standing cable chest press

Question 12

Non neural wrist

Corrective program

Answer 12

Stretch - wrist flexors and extensor

Note- movement that combine elbow extension with wrist flexir extension are good

Activate- same
