What are some major differences you notice between a human brain and a sheep brain?
The difference between the human and sheep brain lies in its size and shape. While the human brain is larger and round, a sheep’s brain is smaller and elongated.

What are two major differences between the sheep brain and the human brain?
A sheep’s brain is elongated in shape, whereas a human brain is rounded. The human brain stem is towards the backbone and downwards, because in the human body the backbone is vertical; compared to a sheep’s backbone which is horizontal, and its brain is directed outwards.
How do you get rid of a sheep brain?
Levering the head open If the cranium has been cracked sufficiently, the whole head can be levered open and the brain and pituitary gland exposed. A boning knife (or scissors) is used to cut the nerve roots and dura mater as the brain is exposed and removed (Figure 8). The brain can be removed whole and intact.
