I've always felt that memorization was just a way to get around not understanding something. It gets you through multiple choice tests, and not much further. You can spit back answers verbatim from syllabi, or what not, but couldn't explain it to anyone if you had to. It's just a stopgap solution that bypasses any meaningful learning. Most memorization fades away very quick, without use, especially at such high volume like in med school. Without looking it up, name the nerves that contribute sympathetic fibers to the pterygopalatine ganglion? Could you? Whats the point in having learned it 9 months ago. It probably faded, the knowledge is functionless. You might end up rememorizing it again for the boards but once again just really to pass a test not any real world, pragmatic use of knowledge. Just facts for the sake of facts. I would venture that most specialists know their material cold because they are required to understand and USE it frequently. Its functional knowledge.
Ok I'm off my soapbox now. With that being said, memorization is a necessary element in the current educational process. If you can't do it, you will struggle. Understanding concepts is great, but inevitably you have to buckle down and memorize a lot of facts. Personally I try to get the concept of the what is going on, feedback loops, reciprocal regulation, etc... and then the names just fit in easier because they have a place in a conceptual framework. Thats what works for me so far.
"You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing -- that's what counts. I learned very early the difference between knowing the name of something and knowing something."
Richard Feynman (1918 - 1988)
