Cervical Nerves

Cervical nerves are the nerves emerging from the 7 cervical vertebrae (C1-C7) and C8, which emerges below the C7 vertebra.

  • The ventral distribution includes the cervical plexus and brachial plexus
  • The thoracic distribution includes the greater and lesser occipital

The course of the cervical nerves converging makes anesthesia possible at the paraspinal subcutaneous muscles.


The primary extensors of the neck include the trapezius, splenius capitis, splenius cervicis, and semispinalis capitis.

Injection Technique

There are 3 possible methods of approach to the cervical plexus: posterior, lateral, and oblique. The posterior route is considered to be the safest. Although the nerve trunks are not directly contacted by this method, but infiltration of the muscle is sufficient enough to produce effect.

Note: Due to the vast network of blood vessels in the neck, aspirating prior to injection is advised.
