Eye Dissection

 Aim- To dissect a cow's eye and look at the different parts of the eye. 

Equipment:

1: Cow's eye

2: Scissors

3: Newspaper

4: Tweezers

5: Rubber glove. 


Method:

1: Set up a tray with newspaper on the desk, the tray on top and the scissors and tweezers in the tray.  

2:  Put on a rubber glove. 

3: Start to remove the excess fat and meat from around the eyeball before dissecting it. 

4: Puncture a hole in the cornea, where the cornea and the sclera meet.

5: Cut around the cornea so that the vitreous fluid leaks out of the eye onto the tray. 

6: Once the cornea has been totally removed you will be able to move the lens from the iris. 

7: Cut the eye in half so that the inside is totally exposed. Once this has been done you will be able to access the retina at the back of the eye. 

8: You should now have placed the retina, lens, cornea and iris on a piece of paper.  

9: The dissection is now complete and all the parts of the eye need to be wrapped up and trashed. The trays and utensils that were needed must be rinsed and the rubber gloves thrown out. 


Summary:

The cow's eye has exactly the same parts as the human eye except for its ability to see better ing the dark.
