Brain Dissection

The myelin makes the signal go faster down the neuron and keeps it insulated. 

Color	Structure	Function
Yellow	Cerebrum	Higher thinking and function
Green	Cerebellum	Balance and coordination
Grey	Brain stem	Breathing, heartbeat, and consciousness

Color	Structure	Function
Yellow	Thalamus	Motor function, emotions, relaying signals to rest of brain, perceive pain
Green	Optic nerve	Bring signals and info from the eyes
White	Medulla oblongata	Autonomic functions, relay signals to other areas of brain
Grey	Pons	Autonomic functions and sleep cycles
Blue	Midbrain	path way between fore and hind brain
Red	Corpus callosum	Connect the 2 hemispheres and send info between
Black	Hypothalamus	Hormone secretion

In this dissection we looked at the different parts of the brain and sorted out the different functions they have. The dissection also relates to what we learned in the distinctions between grey and white matter. We learned that myelin coats neurons which they have to send a signal fast. In the brain stem I noticed there is hardly any grey matter as this is the area that has lots of information coming in that must be quickly sorted. Once it branches off it is still white matter then it turns to grey matter. The branches of white matter are obvious in the cerebrum and the cerebellum. They continually get smaller until it turns to grey matter to communicate and process the information. In the cerebellum the small bumps were clearly seen and able to be separated showing how the brain specializes. Two hemispheres also became apparent in this dissection as they are only connected by the corpus callosum and the meninges holds them together (not attaches) by being in the enclosed area together.
