The '''cervical nerves''' are the [[spinal nerves]] from the [[cervical vertebrae]].
Although there are seven cervical vertebrae (C1-C7), there are eight cervical nerves (C1-C8). All nerves except C8 emerge ''above'' their corresponding vertebrae, while the C8 nerve emerges ''below'' the C7 vertebra. (In the other portions of the spine, the nerve emerges ''below'' the vertebra with the same name.)
Dorsal (posterior) distribution includes the [[greater occipital nerve|greater occipital]] (C2) and [[third occipital nerve|third occipital]] (C3).
Ventral (anterior) distribution includes the [[cervical plexus]] (C1-C4) and [[brachial plexus|brachial plexus]] (C5-C8)
