Definition[Bearbeiten]
The term cervical nerves or cervical nerves refers to the 8 paired spinal nerves that emerge from the neck section of the spinal cord, the cervical cord, and leave the cervical spine. The associated spinal cord segments are numbered C1 to C8.
Anatomy[Bearbeiten]
The cervical nerves branch - immediately after they leave the intervertebral foramina - into anterior and posterior branches.
The anterior or ventral branches of segments C1 to C4 together form the cervical plexus. The anterior branches of segments C4 to C8 form the brachial plexus.
The posterior branches of the cervical nerves supply the neck muscles and the skin of the neck and occiput. They give rise to the greater occipital nerve and the tertiary occipital nerve, among others.
