Cervical spinal nerve 6
From Wikipedia, the free encyclopedia
The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment.[1].
It originates from the spinal column from above the cervical vertebra 6 (C6).
The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm[2], including:
- Subclavius
- Supraspinatus
- Infraspinatus
- Biceps Brachii
- Brachialis
- Deltoid
- Teres Minor
- Brachioradialis
- Serratus Anterior
- Subscapularis
- Pectoralis Major
- Coracobrachialis
- Teres Major
- Supinator
- Extensor Carpi Radialis Brevis
- Extensor Carpi Radialis Longus
- Latissimus Dorsi
Damage to the C6 motor neuron, by way of impingement; ischemia; trauma; or degeneration of nerve tissue, can cause denervation of one or more of the associated muscles. Muscle atrophy and other secondary complications can occur.
