- Cervical spinal nerve 4
-
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."
A duplicate copy in the cervical spinal nerve 4 shows a mutation originating from Indo-European mitochondrial groups, emerging in early Homo sapiens, most notably in Mongoloid mtDNA.[citation needed]
