Brains (dissection)

In our brain dissection we used a sheep brain to look deeper into the anatomy and physiology. In the first birds-eye-view picture, you can see the red pin on the brain-stem, and all the other pins in their respective areas. The brain stem we learned was very fragile. After Kian grabbed it, it became half severed, which made it hard to distinguish some parts later on.

name	function
B-stem	Connecting neurons
cerebrum	Voluntary movements
Cerebellum	Regulates muscle activity

In the brain itself, it is shown clearly where the myelin is present and where it is not. Myelin wraps around axons and help the impulse travel smoothing through. In the picture right above or below, myelinated areas are whitter, compared to the darker grey that represents grey matter. After slicing the brain into two halves, we were able to identify many more structures.

Name	Function
Pons	Relays info from cortex and cerebrum
Medulla Oblongata	Helps with homeostasis and regulates respiration
Thalamus	Sensory, motor signal relay, and sleep
hypothalamus	Maintains homeostasis, creates essential hormones
Corpus collum	Relays information back and forth from both hemispheres
Optic nerve	Relays all the impulse to the b
midbrain	Motor control and hearing senses

.The brain in pictures are very "neat" and all the parts are clearly shown, but during the sheep brian dissection we found ourselves second guessing a lot besides what was grey and white matter.
