• We all have 'em. we all know that our knee bone is connected to our thigh bone, which, by the way, is technically incorrect. a knee is a complex diarthroidal joint comprised of the epiphyses of two long bones and what is technically a sesamoid bone as well as associated soft tissue. This knowledge will become important in the forthcoming questions. It may very well be a question on this test so i hope you were paying attention to that bit of osteological diarrhea of the brain. But do not fear. This test won't be too terribly painful. I'm sure that if you're really stuck and you really care whether or not you get a good score on this test, you can google it... if you must.
