The cervical spinal nerve 2 (C2) is a spinal nerve of the cervical segment.[1] It is a part of the ansa cervicalis along with the C1 and C3 nerves sometimes forming part of Superior root of the ansa cervicalis.[2] it also connects into the inferior root of the ansa cervicalis with the C3.[2]

It originates from the spinal column from above the cervical vertebra 2 (C2).

it innervates the rectus capitis anterior and rectus capitis lateralis muscles, and provides sensory nerves to the trapezius.[2]

the lesser occipital nerve, greater auricular nerve, and the transverse cervical nerve all emerge from C2, with the ladder two shared with the C3.[2]
