When I was memorizing, I used flash cards, which do work, but only if you keep at them for a long time. I also doodled things everywhere. Be warned though, this will creep out your friends. A good idea is picture association. Like, take a word and make it into a picture. You can take something simple like the humerus and picture a bone with Popeye forearms telling a joke. There's your funny bone right there (how many people knew that that was why the funny bone is called the funny bone? Common, it's not funny when you hit your humerus. man, I'm lame). Or, like, Bovine Spongiform Encephalopathy could be a cow with its tongue out, eyes all buggy and holes in it like swiss cheese. Make them as absurd as possible. Hope that it works for you. Good luck!
I fidn that the easiest way to memorize medical terms is by doing simple activities with them. If you search google for activities about the word, there should be some simple things to do that are easy repitition
it's all about the word association you can do for the term.... Like bsb and surrep mentioned... if you can make a funny out of it or think of something nasty that will stick in your mind that you can associate the word with you wont forget it. The other day for some stupid reason I couldn't remeber that she,he,it were pronouns so I turned it into a curse word... shh hee ittt. Now I'll never forget... How silly.
In anatomy, I always came up with strange associations. Like, patella, I remembered as "pat your tella", as in a "knee slapper" joke. Axilla (the armpit), because it reminds me of auxiliary, and that's how you hold a rifle. I know they don't make much sense when I try to explain them, but it really helped with the tests.
