What is a sheep brain?
The sheep brain is quite similar to the human brain except for proportion. The sheep has a smaller cerebrum. Also the sheep brain is oriented anterior to posterior whereas the human brain is superior to inferior. 1. The tough outer covering of the sheep brain is the dura mater, one of three meninges (membranes) that cover the brain.
