Cervical spinal nerve 6

Cervical spinal nerve 6: 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.
