Brain Dissection Analysis

Today we dissected a sheep brain!
1.

 2. brain stem: regulates heart rate, breathing, sleeping, and eating.
cerebellum: recieves information from the sensory systems, the spinal cord and regulates motor movements
cerebrum: has 4 lobes- Frontal Lobe ( has to do movements, emotions, and reasoning), Pariental Lobe ( has to do with movement, recognition, and orientation), Occipital Lobe ( has to do with vision), and Temporal Lobe ( has to do with memory and speech)
3. Myelin increases the speed at which impulses are produced along the myelinated fiber
4.

5. corpus callosum: connects the 2 hemispheres of the brain
optic nerve: transfers visuals from retina to center of brain
thalamus: correlates important processes like sleep and consciousness
hypothalumus: links nervous system to endocrine system
medulla oblongata: center for respiration and circulation. regulates breathing, vessels, digestion, etc
pons: nerves originate here

Relate and Review:
We dissected a sheep brain. The sheep brain had most of the parts that the human brain had. It was easy to tell the different lobes: frontal, pariental, occipital, and temporal. We were able to so so many different parts of the brain that really relate to the human brain that we have learned in class. We labeled each part that we found and we looked up the function. (info and pictures above!) This dissection was really cool and I would love to dissect it again someday, even another animals brain would be cool!
