I have a genetics test on friday that doesn't scare the crap out of me for some reason. I have been asking around and the feeling seems to be mutual. Of all the classes we have, genetics seems to be the slack class. People sleep, do crosswords, day-dream...it's like the days of undergrad. The only real difference is that most everyone still goes to class; we are a guilty bunch. One of the great things about med school is that they bring in guest lecturers a lot who know the topic being taught. One of the problems is that very few of these magic scientists knows how to teach.
On another note, we dissected the arm this week. That's a cool-ass piece of work. Your forearm controls most of your finger movements, and does so by connecting muscles to these pencil-thick tendons, like cables run through a pulley system, that run all the way up the forearm, through the wrist, and into the hand. They get routed through a little tunnel and held down by a ligament. It honestly looks like a thick piece of canvas is just stretched over the top. It's tough as hell and narrow. Called the carpel tunnel and that's where carpel tunnel syndrome gets its name. If something swells, everything rubs up against everything, including the thick nerve that runs through there. Thought that was cool.

In that movie "Unrest", the professor pulled on a muscle/ tendon of the arm and it would move a finger (phalange....I love that word!!). I thought that was a pretty cool trick! What else have you guys disected? Do you go in any specific order or do they just give you random body parts/ organs?
