Find out when your local university's introductory anatomy class runs and show up. These classes tend to be 250-400 people so bring a notepad and sit at the back, it's highly unlikely that anyone's going to ask you for proof of enrollment. Right at the beginning, first couple of classes is when they'll cover the movements (flexion, extension, adduction, abduction, rotation) and position indications (superior, inferior, lateral, medial, proximal, distal, superficial, deep). You need to know these terms before you can learn much, because everything in anatomy is referred to with respect to something else (i.e. the the phalanges are distal to the carpal bones).
Short of that, you could pick up some anatomy flash cards - I didn't use them but I had two textbooks. Others I know say they made life easier for them at finals time. You probably want to shop around for a good set if you choose this route, these are just something I found quickly.
Alternately, you could look into picking up a textbook on the matter, Grant's Atlas of Anatomy was a lot more consistent and helpful than google in visualizing all the bones and muscles - it's just an atlas though, not an instructive text so it doesn't explain much, just shows connections and structure.
I'm sure you've seen it as well but wikipedia's outline of human anatomy (Outline_of_human_anatomy) gives you a good reference from which to start going topic by topic.
To be honest anatomy is one of the most complicated subjects I've ever learned (and don't take me for any kind of expert, far from it) and I'm not aware of a very straightforward and streamlined approach to tackling it. I found it sort of like squatting, you just have to start somewhere and stick to it, and ask for help when you need it.
Good luck!
