Basic Anatomy:
The meninges:
Dura mater help protect from injury
Underneath the Duramater, we have
the Arachnoid that connects the Dura
mater to the pia mater (spongy like
structure)
Pia mater thin surface that protects the
brain
The arachnoid holds the Dura and the
Pia mater
In the PNS , we lose the arachnoid
mater but we still have 2 layers , Duramater and Pia Mater
Circulation of the cerebrospinal fluid
Four spaces filled with CSF in the brain
CSF circulates around the brain and also circulates
through the end of the spinal cord and comes back up
to the brain
The CSF circulates in the subarachnoid space
