The Sheep Brain

The Sheep Brain Dissection 

In this dissection, we started by examining the exterior side of the brain, pinpointing the cerebrum, which controls the integration and data sorting, the cerebellum, which controls the motion and balance of a person, and the brain stem, which connects the spine to the brain and connects to the pons.

Next, we cut the brain longitudinally so that we could see the parts of the brain. Inside we started from the brain stem and went to the pons, which controls the circulation of the blood, and then the medulla oblegada and mid-brain which control the digestion in the body. Then comes the thalamus, which sorts data in the brain, and the hypothalamus, which controls the hormones that help with the homeostasis. Lastly, we have the Corpus Callosum, which separates the left and right hemisphere of the brain, and the Optic nerve, which sends impulses from the retina of the eye to the brain for functioning.

Lastly, we saw the difference in the white matter and the gray matter. The white matter includes all of the myelin that makes up the myelin sheath on the axon that helps send electric signals through the brain at a faster pace.
