This opaque covering is the dura
The meninges cover and protect the brainFrom outer to inner they include:1. Dura
-tough outer layer we took off2. Arachnoid
-The Cerebral Spinal Fluid (CSF) flows between the Arachnoid and Pia layers and serves to nourishand protect the brain & spinal cord.
3. Pia-pearly layer extends intothe sulci

Cerebellum
The shiny coating is the Pia Mater
The Pia Mater is the innermost meningeal layer.It extends into the sulci.

This is the URL to a sheep dissection lab created by five students in the bi-college (Haverford and Bryn Mawr) community: Jessica Kuhn, Jessica Magid, Karen Revere, Elizabeth Caris, and Gray Vargas through science education at Bryn Mawr College. It is a fantastic site to explore the brain. Not everything you will learn will be on a test BUT remember that educating yourself in your field is NOT about what is going to be on the test .
TRY THIS TO TEST YOURSELF!!
