We had to do cats, which repelled me at first because I'm a cat person. (Now my alma mater has actual human cadavers, which I would have vastly preferred.) But once we got going on the cats, they more or less ceased to be cats, and became a fascinating collection of muscles and bones and tissues, some of which are amazingly similar to humans!
In the meantime, keep your eyes on the prize.........you're doing all of this to become a nurse.
Focus on your goals, not the 'critters' in front of you, and you'll get through it, I promise!
