Gross anatomy was one of the courses I feared most about going into dental school.

I even mentioned it in my dental interview. I think they appreciated my honesty!
Thankfully it wasn't as bad as I thought it would be. Our cadaver was, how can I say this, not as fresh as some other ones in the lab. The body was pretty brown and a little dried up. It kinda reminded me of Kentucky Fried Chicken oddly enough.

If it helps you any, usually when you're working on the body, they have a cloth covering the face. I believe that all the blood has been drained from the femoral artery, and they run formaldehyde through the circulation. Or do they immerse the entire body in it? I'm not certain.
We started on the chest area first, and I had to let my lab partners do most of the work since it took me a while to get used to the whole thing. LOL sure call me a wuss, but they didn't supply any gloves for us in the lab. After a while people were buying their own boxes of latex gloves so that helped. The smell isn't too bad. It's just a chemically smell mostly.
Our cadaver's head was pretty shriveled up so it didn't look so real which made it easier to work on. Don't worry - you're not the only one with the heebie jeebies thinking about dissecting human bodies. Try to concentrate on learning the anatomy rather than focusing on your fears.
It's actually kind of neat after you've removed the heart and lungs. The chest cavity is just a compartment with the spine and esophagus running down the back area. You end up seeing people in a whole new light.
