Cow Eye Dissection Introduction: The eye is a special sensory organ with a complex structure and function. The objective was to gain a better understanding of the structure and the function of the eye. In this lab, we set out to dissect a cow's eye and identify the different parts of the eye. We did this by removing the fat and muscle surrounding the eye to reveal the sclera, and be able to make an incision in the middle of the eye to reveal the inner parts of the eye; the vitreous humor, ciliary body, choroid and retina. Once all the parts were identified, we received a clearer understanding of how each part of the eye affected the whole eye. Materials: Gloves Goggles Dissection Tray Dissection Kit- scalpel, pins, scissors Paper towels Cow eye Methods: We started off by carefully removing all of the excess fat and muscle tissue surrounding the eye with a scalpel or scissor. After it was removed and the sclera was visible, we made an incision around the middle of the eye to where one half of the eye was the anterior part and the other posterior. We proceeded to carefully remove the clear gelatinous liquid know as the vitreous humor. Next, we took the front half of the eye with the cornea and with a pair of scissors we cut off the cornea. This allowed us to locate the iris. We then flipped the front part of the eye to locate the ciliary body. After locating the ciliary body we took out the lens by pulling it out. With this done, we removed the retina, a thin tissue like material, which is located in the posterior part of the eye. With everything removed, we were able to observe the choroid coat, which is a very shiny colorful tissue. Data: Fat and Muscle Tissue- thick gray tissue that covers most of the outer part of the eye. Sclera- white outermost layer of the eye covered in fat and muscles. Optic Nerve- stiff round protuberance coming out of the
