Brain Dissection

This dissection was all about the brain. It wasn't as much dissection as it was discovery and viewing the main parts. We had only a few cuts, but we were able to identify the cerebrum, cerebellum, brain stem, corupus collosum, medulla oblongata, pons, midbrain, thalamus, and hypothalamus. After figuring out the location of each of the structures we looked through our notes to discover the function. The following functions go as follows. Firstly, the cerebrum in the brain provides for higher brain functions such as thoughts or actions. The cerebellum coordinates and regulates muscular activity. The brain stem transports information to and from the brain.  The myelin is the coating on the outside of a neuron. The myelin's function is to increase the speed of nerve impulses. The optic nerve main purpose is to transfers visual information from the retina to the visual centers of the brain from electrical impulses. The corpus collosum is a large bundle of neuron fibers that connects the two hemispheres of the brain. The midbrain controls breathing. The medulla oblongata aids in digestion. The pons helps with circulation.  Finally, thalamus' main function is to sort data and the hypothalamus' main function is to maintain homeostasis.
