What are the main differences and similarities between a sheep and human brain?
1 Sheep heart – The sheep heart is very similar in size and shape to the human heart – slightly larger than the average human heart, but otherwise very similar. 2 Sheep eye – The sheep eye is identical to the human eye in all major respects. 3 Sheep brain – The sheep brain has the same basic plan as all mammalian brains, including humans. Compared to a human brain, the sheep brain has a relatively smaller cerebral cortex and consequently a relatively smaller overall size. The other major parts are identical in terms of gross anatomy.
