Abstract

There are two major subdivisions of the nervous system: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS consists of the brain and the spinal cord. Whereas the PNS consists of the nerves outside the CNS. These nerves bring sensory information to the CNS and transmit commands (i.e. motor information) from the CNS to the body. The PNS has three components, the Autonomic Nervous System (ANS), somatic nervous system (spinal nerves), and the cranial nerves.
