when testing to see if a wire is "hot"...
so, apparently, electricians know a bit about anatomy... just ask them how they test if an electrical wire is "hot"--live with electricity, that is... the answer you'll often receive is that they brush the back of their hand (or the posterior, as we call it here) against the wire, not the front... if i were to do it without thinking, i'm sure that i would choose the front...
but that's wrong, because if the wire is live, the electricity now running between your hand will likely force your hand close--those muscles in the hand that flex your hand will contract with the electrical impulse--right on the wire, which will probably mean bad things for you...
though if you brush your hand against the wire, it'll force your hand close, but you'll close it away from the wire and will be spared what is probably a pretty nasty electrical burn...
anyway, in anatomy we had a md/phd hand surgeon come and talk about his work and the kind of things that are possible in restoring hand (and general upper limb) function for individuals... it's pretty amazing stuff, honestly... my mom would have loved it--all that hand surgery talk... it's an amazingly complicated part of the body, and ingeniously designed...
also, i went to an emergency medicine interest group meeting today, which was great. the meeting was better than the free lunch served, but those sandwiches were easily a close second... i haven't had tuna that good in quite a while... well, at least since July 14th...
i'm staring down a midterm in microanatomy (histology) tomorrow, and on monday we have out first anatomy exam, which the TAs have informed us is killer, so i'm not doing much more than going to class every day, going home for a bit to eat something, watch 20 minutes of sportscenter, and then heading right back to the library for four or five hours of studying, and then maybe an hour or two more at home after it closes... i think i'm getting a lot better at studying--seems like it's a muscle, and after a few weeks, i'm really getting a bit stretched out...
something else really interesting happened today, but i can't think of it for the life of me. the memory has been replaced with info on the extensor carpi radialis longus and the lamellae of compact bone... ugh...
when all this is over next monday night, that's going to be pretty sweet...
cheers,
