I agree with Carbon. If you're taking it just to have a better shot at med schools or if you think it's going to help you in med school, don't bother. You're better off taking something that genuinely interests you. Most of my electives ended up being English classes, and I'm so happy I went that route instead of taking a bunch of bio classes that didn't interest me.
I was a biology major and I did a concentration in vertebrate anatomy and physiology, so I took lots of anatomy classes (human and other) and absolutely loved them. I had to take the nursing human anatomy class as part of the concentration, and I thought it was one of the most pointless classes ever (all you tarheels-- stay away from biol 045!! you don't need it and it will bore you to tears!!). However I also took human anatomy/physiology through the Exercise and Sports Science Department, and absolutely loved it.
hehe-- my favorite a/p class was mostly based on squid. best class ever. 😎
