8th Grade Cow Eye Dissection |
|
When we dissected the eye, we learned many new things about it. We learned about what it is made of and what is inside the actual eye. Although we could make out most parts of the eye, our specific part; the ciliary body was hard to find and see. During the dissection we both tried to make out the ciliary body but it was just to hard and we could not see it. It was particularly hard to see the ciliary body because of the gelatinous Vitreous humor. Because of this, we could not learn as much about our part of the eye as we would be able to if we could see it and touch it. Although we did not see the ciliary body I still feel we got a much better feel for what the whole eye is like, and therefore understand the ciliary body better.
The first thing we did when dissecting the eye was cut the fat off. After cutting the fat off we cut around the cornea and removed it. Then we played around with the eye and removed the lens and iris. Once the lens and iris were removed we took out the slippery Vitreous humor. Once that was all taken out the remaining parts of the eye such as the sclera and tapetum were very similar in texture. All the remaining things were durable and tough. If we could have found the ciliary body it would have been very similar to this. It would have connected to the suspensory ligaments which connects to the lens. Though we didn't see the ciliary body we have a much better picture of what it we be like.
One of the main functions of the ciliary body is to focus the lens. The ciliary body controls the suspensory ligaments which focus the lens making it easier to see things closer and farther away. When the ciliary body pulls the lens taut, it makes the lens focus on things that are far away. When the lens is loose it is easier to focus on things that are closer away.This is illustrated above.
