As the students filed in, Elliot fussed with an ivory-colored model skeleton. In an attempt at whimsy that might have failed, she had put a top hat on it and fastened a boutonnière to one rib.
"Hi, people, this is my second TA for the day, Mr. Bones, who is here to help me tell you about the
human skeletal system -- which is kind of the framework that holds our entire bodies together. Mr. Bones -- who is, so you guys don't freak, just a model -- has about 206, well, bones, but I am not going to make you memorize every one of them just yet. But some of the more important bones in the
front are the skull or cranium, the jaw or mandible, the sternum, the rib cage, the pelvic girdle, the humerus, ulna and radius in the arms, and the femur, tibula and fibula in the leg." She pointed to each part as she talked.
"If we
spin him around, you can see the spine, the coccyx -- if you ever take yogilates, that's the "sit bone" -- and, because of the way he's hung, a better view of the bones in his hands and feet."
"Each of these bones is there for a reason." She went on to explain the intricacies of how the skeleton fit into a whole, possibly at slightly too much length, before pointing to the back of the room. "There are two
model skeletons back there that have been taken apart -- it's your job to work as groups to wire them together by the end of class. And I
wired another one up so you guys can make it do tricks, just please don't break it. For extra credit, there's a
computer game you can try that's really more advanced than I expect you to be this week, but if you want to try it before next class, I will be all impressed with you."
"And don't forget to draw on the body tracings we made last week. You don't have to draw the whole entire skeleton, just part of it so you remember what we went over -- a skull or spine or coccyx or something."
"I think that's it for today; I'll be hanging out up here with Mr. Bones if you need me."
