The Shoulder Is A Complicated Joint

Today we got to practice doing our very first physical exam! It was really fun and cool to find the different structures we've seen in our cadavers on each other. We learned how to test for rotator cuff tears and how to differentiate which muscles are affected (ones used to lift your arm above your head, ones to reach behind and scratch your back, etc).
Fun fact: Try moving one arm as if your are scratching your back. See how high up you can go. Now try the other arm. Your non-dominant hand can go higher than your dominant hand.
Now put up your arms like you're on a roller coaster, palms forward, elbows locked. See how far backwards you can go. Your dominant arm can go farther back than your non-dominant. Cool huh?
Also, I have found that residual formaldehyde smell on my hands after lab doesn't really bother me anymore. If I cut it to down to a manageable level, then eating, studying, leaning my head on hands, etc are fine. This is a good thing since the scent is really hard to get to rid of after 3 juicy hours of lab, but I'm starting to wonder if other non-med student people can pick up on this lingering perfume.
