= **__The meninges and the cerebrospinal fluid__** =

**__Outcomes__**

**To understand the arrangement of the three meningeal layers that surround the brain.**

**To appreciate the arrangement of the ventricular system of the brain and the composition of the cerebrospinal fluid.**

**To understand meningitis and hydrocephalus.**

**To appreciate the embryology of the brain.**

__**Learning objectives**__

After reading this SDL you should be able to: **- Name the three layers of the meninges that surround the brain** **- Name all the dural sinuses and map out their course** **- Name and describe the 4 dural partitions of the brain** **- Name all 4 ventricles** **- Define cerebrospinal fluid, name its functions and recall the normal cerebrospinal pressure range** **- Name the structure that produces cerebrospinal fluid and be able to locate it** **- Understand what meningitis is, what its symptoms are and how it is investigated and treated** **- Understand what hydrocephalus is, what its symptoms are and how it is investigated and treated** **- Name the different parts that make up the hind brain, midbrain and forebrain.**

I created this wikispace to help Swansea GEM students year two understand the anatomy of the cranial meninges and the ventricular system within the brain and the embryology of the brain.
