The PNS Supplement to the 7th Edition of Human CNS Structure provides a comprehensive introduction to the peripheral nervous system (PNS) for beginning chiropractic students studying neuroanatomy. The text reviews foundational nervous system organization, sensory and motor pathways, and cranial nerve anatomy before exploring the individual cranial nerves, spinal nerves, plexuses, and the visceral nervous system. Topics include cranial nerve functions and clinical considerations, cervical and brachial plexuses, thoracic, lumbar, sacral, and coccygeal spinal nerves, autonomic pathways, and the anatomy of special sense organs such as the eye and ear. The text is specifically prepared to aid the first-year chiropractic student in following lectures on the neuroanatomy of the central nervous system (CNS) and peripheral nervous system (PNS). Clinical applications and accessory structures of the nervous system are explored.

The spinal nerves are attached to the spinal cord
Shortly after combining into a mixed spinal nerve, a meningeal (recurrent meningeal, sinuvertebral) branch is given off
The mixed spinal nerve divides into two (primary) rami
Sympathetic Chain Communications
Cervical Posterior Rami

Brachial Plexus

Thoracic Spinal Nerves
Lumbar Spinal Nerves
