A&P Muscle Practical Final

On Tuesday, I have my practical final for my Anatomy & Physiology class, and it's on the muscles. We have to know the muscle name, origin, insertion, and action of each muscle we were assigned. The origin of a muscle is pretty straight-forward, it is where the muscle originates, and the insertion is where the muscle terminates, or ends. When a muscle is flexed, like the biceps brachii for example, the insertion moves towards the origin. There are 42 in total we are responsible for, and it has been pretty ambiguous as far as how the practical will be set up. We had a bone practical for our midterm grade, which was pretty straight forward: different bones were set up around the perimeter of the lab's benches, with features tagged A/B/C/D, half the class had an A/C practical and half had B/D, where they were responsible for identifying A&C or B&D. The reason I'm not sure about the muscle practical final is that there are a lot of models in the A&P lab but we haven't had time or access to become familiar with them, which could potentially be a problem, especially for people who aren't so spatially-oriented that they can look at a picture in a lab text and relate it to a 3D model, pointing out origins, insertions and actions. Here are the muscles I'm responsible for (I realize this could be a lot worse!):
