What Are is Nervous System Flashcards
What is the nervous system made up of??
The nervous system is made up of two parts, the central nervous system (CNS) and the Peripheral nervous system (PNS)
What do both of the systems do together?
Both parts work together to allow for rapid communication within our body by sending electrical signals along nerves.

What is the peripheral nervous system made up of?
The peripheral nervous system is made of all of the nerves that connect to our central nervous system. It is important as it allows for messages to be sent to the CNS for processing and will then transmit introductions back to muscles or organes so that a response can happen.
What are receptors?
Receptors and sense organs( groups of receptors) allows us to detect stimuli
