Central Nervous System (CNS)

---

The central nervous system is comprised of the brain and spinal cord. The brain is contained within the skull, and the spinal cord is contained within the spinal vertebral canal. The brain is covered, and protected, by the meninges. The meninges are comprised of three layers: the dura mater (the outermost layer), the arachnoid mater (the middle layer), and the pia mater (the innermost layer). Nerves arising from the brain and brain stem are the cranial nerves whilst those arising from the spinal cord are the perhipheral nerves.

Peripheral Nervous System (PNS)

---

The Peripheral Nervous System includes both cranial nerves and spinal nerves, and is commonly divided into the somatic nervous system and the autonomic nervous system. The autonomic nervous system contains thesympathetic nervous system and the parasympathetic nervous system as well as an enteric division.
