The nervous system can be divided into two types from the anatomical point of view: Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
The peripheral nervous system is the part of the nervous system formed by nerves and ganglia. Its primary function is to take information from the peripheral organs to the peripheral nervous system and bring the responses of that system back to the organs. Therefore, this system is responsible for conducting information. It is formed by the somatic and autonomic nervous systems.
