This past week, Coach Sasser and his students conducted a variety of dissections. They analyzed a sheep brain and a large cow eye. During the sheep brain dissection on Monday, his students paired up, then using a scalpel and tiny scissors they separated the main brain from the tiny brain; the cerebellum. There are many layers protecting the brain that his students had to identify and remove very carefully. On Wednesday, his students also dissected a cow eye. Fatty tissue had to be removed very carefully in able to view the eyeball itself and the optic nerve. The students then sliced the eyeball in half and removed the hard round lens and the vitreous body (“the jelly” inside the eye). Inside, one could see the retina at the posterior end of the eye, the iris, and pupil at the anterior side. Throughout the experiment, his students further learned how the brain functions and also how the eye functions.
