For the first lab, our instructor failed to tell us that we would be shirtless, as we would be drawing each other's shoulder girdles. I was one of the lucky ones that wore a sports bra to class, but it didn't make it any less awkward. Both of our instructors are male and to be able to identify the shape of bones requires significant palpation.
I know we are supposed to be professional and mature about this whole thing, but I can't help but dread the day that we do the anterior and posterior hip complex!
