Guess what I cut up today? A cow eye!

This year I am in biology. Yeah, that's right. I get to dissect stuff. As some of you may remember, I dissected a worm a while ago, so I'm not all new to this business of dissection. My supervising teacher came to help me with the process. The pictures pretty much say it all, so I am going explain it step by step with them. Enjoy!! :)



The cow eye, before I did anything to it.

Cutting the muscle and fat away.

Muscle and fat all gone!

Cutting the cornea open.
Removing the cornea.
All taken apart.
I think you can guess what that is. :)

The back of the eye.
Tapetum, reflects light back through the retina.
The lens.

The Pupil
The front of the eye, from the inside.
The back half of the eye.
So there you go. I had a pretty awesome time. Strange, huh? Lots of people wouldn't say that, but I thought it was pretty amazing. And cow eyes are a lot like human eyes, so that kind of gives you an idea of what we see out of everyday. Awesome, right?
God bless,
