Comparing the Sheep Brain to the Human Brain – A Visual Guide to Use During Sheep Brain Dissection Laboratories Margarita Bracamonte, Ph.D Northland Community & Technical College, East Grand Forks, MN
2
Several Community and Technical Colleges currently do not have a human cadaver laboratory to teach human anatomy and physiology labs. To learn about the human brain anatomy, sheep brains are usually dissected in anatomy and physiology laboratories at Community and Technical Colleges.
3
Therefore, the next slides can be used during the sheep brain dissection laboratory to visually compare the sheep brain to human brain structures with the goal to learn the anatomy of the human brain.
4
How much does the sheep brain weight compared to the human brain?
140 grams* 3 - 4 pounds *1 pound = grams

The human brain (and sheep brain) is made up of four parts:
1. Cerebrum Human Brain 2. Cerebellum Continues… Sheep Brain
