Guest rainnoodle Posted August 22, 2001 Report Share Posted August 22, 2001 Hello, I picked the freshwater along the same lines of reasoning as stated in the previous of the posts...but there still seems to be some discrepency... So, I looked on the web and stumbled on to this site from Georgia State University www.gsu.edu/~bioslp/Bio3840/H2O.htm It states on the 2nd paragraph right beneath "2. Aquatic vertebrates " and says that "No loop of Henle exists in freshwater vertebrate"... Link to comment Share on other sites More sharing options...
Guest BCgirl Posted August 22, 2001 Report Share Posted August 22, 2001 Well, I don't know what's up with that question since the Mac page says that marine nephrons don't have a loop of Henle either... Link to comment Share on other sites More sharing options...
Guest Kirsteen Posted August 22, 2001 Report Share Posted August 22, 2001 Hey there, The answer may lie in what parameters the AAMC folks set out in the question, i.e., the environment that the fish started out in to begin with. I, too, did a wee bit of investigation regarding this mysterious lack of Henle and found a couple of sources that mentioned that both salt- and freshwater fishes having nephrons sans Henle. I can't remember how the MCAT question was worded precisely but it sounds like, no matter what environment you're in, if you're a fish, you don't want a LoH.
