Is the central nervous system the same as nervous system??

Because in my cgp book it says the nervous system is made of neurons but the CNS is made of a brain and spinal cord??

Nervous system: central nervous system + peripheral nervous system.

The central nervous system is the brain and spinal cord.
The peripheral nervous system comprises the nerves that leave the brainstem (cranial nerves) and spinal cord.

The nervous system as a whole is made up of two components: the central nervous system (this means the brain and spinal cord) and the peripheral nervous system (this means the nerves that go from the spinal cord to the rest of the body).

Maybe an image would help:


Ignore the words on the picture, they'll just confuse you. Everything in yellow is the central nervous system and everything in green is the peripheral nervous system. Together they make up the nervous system of the body.

They're not the same thing as such. The central nervous system is just one part of the nervous system.

The nervous system means every nerve in the body.

The central nervous system means only those nerves in the brain and spinal cord.

The peripheral nervous system means only those nerves outside the brain and spinal cord.

Together the central and peripheral nerves make up the nervous system.

Long story short, the CNS is primarily the brain and spinal cord - the nervous system includes the neurones which essentially travel from all receptors which are found across the whole body.


Ok so the nervous system goes through the CNS?

The CNS is a subset of the whole nervous system.
