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 (C2) and third occipital (C3). Ventral (anterior) distribution includes the cervical plexus (C1-C4) and brachial plexus (C5-C8) [WP,unvetted]. cervical nerve tree nervus cervicalis NCIT:C32299 Innervates: sternohyoid muscle, sternothyroid muscle, omohyoid muscle[WP] UMLS:C0228815 neuronames:2351 spinal nerve cervical spinal cord
