Anatomical terminology [edit on Wikidata]

The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment.^[1] C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami).

It originates from the spinal column from above the cervical vertebra 1 (C1).^[2]

The dorsal root and ganglion of the first cervical nerve may be rudimentary or entirely absent.

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
