The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment.[1] C1 is unique in that all other spinal nerves have both sensory and motor fibres, whereas C1 only carries motor fibres.
It originates from the spinal column from above the cervical vertebra 1 (C1).
Muscles innervated by this nerve are:
- Geniohyoid muscle- through Hypoglossal nerve
- Rectus capitis anterior muscle
- Longus capitis muscle (partly)
- Rectus capitis lateralis muscle
- Splenius cervicis muscle (partly)
- Rectus capitis posterior major muscle
- levator scapulae muscle (partly)
- Thyrohyoid muscle – through hypoglossal nerve
- Omohyoid – through Ansa cervicalis
- Sternohyoid – through Ansa cervicalis
