Sheep Heart Dissection Analysis

In this lab, we dissected a sheep's brain. We made two basic cuts into the brain: on the medial plane and a cross sectional cut on the cerebellum. With these cuts we were able to observe the main structures of the brain and the many different parts that enable it to function properly. This relates to what we have learned so far because we were able to take what we have learned in class and apply it to an actual brain. It was basically a step up to The Clay Brain, where we made our own model of the brain with play-doh. Also, we were able to see the features of each structure to better understand how it enables the function of that feature.
1. Drawing of brain:

This is a picture of the brain with pins pointing out the main structures. Red: brainstem, black: posterior side, green: cerebellum, yellow: cerebrum, white: anterior side 

2. Function of structures:

3. The myelin insulates the axons, which allows the signal in the brain to not be interrupted and travel at a faster pace.

4. Drawing of cross-section:

This is the picture of the cross-section of the cerebellum. The grey matter can be identified by its darker color. The white matter is the lighter sections.
