cervical nerve

1. Any of the eight pairs of spinal nerves that originate in the cervical segments of the spinal cord. They are abbreviated C1 to C8. The first cervical spinal nerve (C1) emerges from the spinal canal above the first cervical vertebra; the eighth cervical spinal nerve (C8) emerges from between the seventh cervical vertebra and the first thoracic vertebra. Cervical spinal nerves innervate the neck, shoulders, and arms.
2. A motor branch of the facial nerve (CN VII) that emerges from the lower end of the parotid gland and runs down behind the angle of the jaw to innervate the platysmus muscle.
