Sheep Brain Dissection

We dissected a brain!  First, we took off some of the meninges. Even though the two hemispheres of the brain are only connected by the corpus callosum, it wasn't easy to pull both sides apart because of the meninges. I also noticed that in some of the parts where where the meninges were removed, the brain had lost it's structure. We marked the parts of the brain with pins. Then we cut the brain into the right and left hemispheres. At first, it was hard to identify some of the parts like the optic nerve, even though they were clearly seen in the book. Lastly, we cut the cerebrum to see the center of it. It was very easy to tell white matter from gray matter.
