The cervical spinal nerve 5 (C5) is a spinal nerve of the cervical segment.[http://www.ama-assn.org/ama/pub/category/7173.html American Medical Association] {{Webarchive|url=https://web.archive.org/web/20071220035105/http://www.ama-assn.org/ama/pub/category/7173.html |date=2007-12-20 }} Nervous System -- Groups of Nerves

It originates from the spinal column from above the cervical vertebra 5 (C5). It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the musculocutaneous nerve.
