the author has proved experimentally ( in two dogs ) that there is reflex hypertonia of the tensor palati muscle , synchronous with the 'shortening ' reaction of the tensor tympani muscle in response to its `` '' static '' '' relaxation during the gradual passive inward displacement of the drum resulting from the negative intratympanic 'dip ' due to absorption of air imprisoned within the middle ear .
