Sheep Brain Dissection Essay

I expected the sheep brain to be much larger than it was in size, I did not expect the brain to be as small as it was. The sheep brain dissection lab was done in order to help students understand how important the structures and functions are in the human brain. A few external details I was able to identify were the frontal, occipital, temporal and parietal lobes as well as the difference between gyri and sulci. Some internal structures I struggled to point out was the hippocampus and the pineal gland, in the future, I would do a further analysis of the clear difference between these two features. Doing the dissection with my partners was very interesting and it was a lot easier to see the difference between most features on an actual sheep brain. We …show more content…
There are many glands and ventricles and parts in the brain that are a huge contribution and every piece in the brain has an important function. Conclusions I might have drawn based upon the structure is that the external structures have the biggest functions since every part of the brain is rather big, except for the frontal lobe in a sheep’s case. The internal structures are as important in the anatomy of a brain as the external structures. In Roger Sperry’s brain dissection was a dissection in which he made a cut right in the middle. Phineas Gage was a man who survived an incident with an iron rod that over 3 feet long. This rod ruined the left hemisphere of his brain and Phineas was knocked unconscious and he was treated by Doctor John Martyn. When being treated the doctors discovered that damage to the brain specifically any lobes can lead to changes in the personality changes in the person. A frontal lobotomy is the process in which the links of the brain are separated. It is basically an operation that disconnects some of the parts of the brain that are tied together and correspond. The purpose of frontal lobotomy is to try to fix behaviors by cutting some of the less important
