What are the names of the forelimb nerves

Suprascapular
Subscapular
Musclulocutaneous
Axillary
Medial
Radial

1

Suprascapular
Support..
Innervation...

Lateral shoulder support
Supraspinatous
Infaspinatous

2

Subscapular
Support..
Innervations..

Lateral shoulder support
Supraspinatous muscle
Infraspinatous muscle

3

Musculocutaneous
Innervations..
Damage..

Motor- brachialis muscle
Biceps brachii

Sensory- cranial and medial aspect of elbow
Medial aspect of antibrachium

Damage- loss of elbow flexion

4

Axillary
Innervations..
Damage..

Motor- Deltoideus + treres major muscle

Sensory-lateral aspect of shoulder and brachium

Damage-compensation by latissiumus dorsi and long head triceps

5

Medial
Innervations..
Damage..

Motor- carpal and digital flexors

Sensory-caudal and palmar aspect limb, dorsal aspect 5th digit

Damage- loss of distal limb flexion

6

Radial
Innervations..
Damage..

Motor- extensors of elbow and extensors of carpus and digits

Sensory-Dorsal and cranial aspect limb, except dorsal aspect 5th digit

Motor damage- proximal can't extend elbow, can't weight bear
Distal can't extend carpus, if triceps intact then can still extend elbow


7

Brachial plexus..
Damage..

C5 C6 C7 C8 T1 T2
Limb can't retract/adduct, flex/extend or weight bear
