Hey Milum: Why didn't you ask where "knee jerk" came from. It is one of those stupid parts
of a physical exam that is ttraditional, but very unlikely to yield and useful information. It is
part of neurological exam, and involve tapping the tendon just below the kneecap, which is
supposed to elicit brief contraction of quadriceps (I think). Long ago late stages of syphilis
might disable it. I can't think of anything else of much interest about it. I used to give
examiners a bad time, because mine is not readily elicited. I assured you Treponema pallidum
has never been a pal of mine. Actually I guess the cute little corkscrews got a new name. I'll
have to go check on that. Reminds me of definiton of alimony - the f-ing you get for the
f-ing you got. The corkscrews you get.......
