Yesterday, the students performed their second round of dissections, this time on sheep brains and cow vertebra. In the sheep brain dissection students do a medial cut resulting in the brain being cut in half. Students then go on to differentiate structures in the brain. During this time students are learning the different planes of orientation of the brain, and distinguishing between major structures such as the hemispheres, cerebellum and more. In the cow vertebrae dissection students distinguish gray matter from white matter. They then make incisions to separate the dura mater, arachnoid mater and pia mater. Students then further discussed the importance of the spinal cord in the human body and how it relays information from the brain to the rest of the body. As you can see, they had alot of fun with this!
