Cervical spinal nerve 4: Information from Answers.com

The cervical spinal nerve 4 (C4) is a spinal nerve of the cervical segment.^[1].

It originates from the spinal column from above the cervical vertebra 4 (C4).

Its control of the thoracic diaphragm has inspired a medical mnemonic: "Cut C4, breathe no more."
