Brain and Spinal Cord (CNS) Anatomy Support structures –(bone) –meninges –cerebrospinal fluid (CSF) Protective structure –blood-brain barrier General arrangement –distribution of white and gray matter

Meninges A general term which refers to all three connective tissue envelopes of the brain. The dura mater, arachnoid and pia mater cover both the brain and the spinal cord; cerebrospinal fluid lies within the space between the arachnoid and the pia.

Ventricles - brain spaces filled with cerebrospinal fluid

The cells lining the ventricular system function as a transporting epithelium whose cilia have a role in circulation of CSF. (note blood vessel) Ependymal Cells

Without looking at any sources - write out the 12 cranial nerves, in order
