Brain dissection

Today in class we dissected a sheep´s brain. We started by observing the outside of the brain and then made our first cut. We made a longitudinal cut first and made a horizontal cut latter just to see the difference between white and grey matter. Here are some pictures/ explanations of this lab.

The Cerebrum's function is to interpret sensory and neural functions relating to voluntary movements.

The cerebellum regulates muscle activity.

The brainstem connects signals from the body and the brain. 

The function of the myelin in a neuron is that it helps the signal flow and it is wrapped around the axon. 

The thalamus helps regulate sleep and sensory input while the hypothalamus maintains homeostasis. 

The optic nerve connects images from the retina to the brain.

The medula oblongata regulates breathing, digestion, sneezing, swallowing, and other vital functions.

Pons is the bridge between the cerebrum and the cerebellum.

The midbrain regulates temperature, vision, hearing, and motor control.

The corpus callousum is the bridge between the right and left hemisphere of the brain.
