Cranial nerves are named I to XII, determined by their skull exit site (anterior to posterior). Spinal nerves are divided into 8 cervical, twelve thoracic, five lumbar, 5 sacral and 1 coccygeal nerve, based on vertebral degree from which they occur. In certain regions of the body peripheral nerves interconnect, building neural networks referred to as plexuses. Notable plexuses tend to be the:
