In this photo during neurosurgery, you can see the layers of the head removed & retracted until the brain is exposed.
First, you see the retraction of the scalp. Then you can see the top of the skull cap, or calvarium. After that you can see the dura mater of the meninges peeled back (the meninges is the protective covering over the brain & consists of the dura mater, arachnoid mater, & pia mater), finally revealing the cerebral cortex of the brain. You can even see the meningeal blood vessels.
