==Possibly False Etymology== 

 I believe the explanation of the Greek word 'histemi' as literally meaning 'to stand equally' is incorrect. I think that a physiologist did this using a dictionary nad was mislead by the is- part in "istemi" [sic], as isos means equal in Greek. However, it's "histemi", not "istemi", and it's the basic Greek word for "to stand", "to put". I will correct all of this now.
