Fig. 7. (A) Responses of the tympanic membrane (black), stapes footplate (red) and parotic crest (green) of a male frog (SVL 131.1 mm) prior to surgery on the ascending process. (B) Responses of the same structures after the ascending process of the extrastapes had been severed. Note that the response measured from the footplate has fallen and now approximates that of the `background' response of the parotic crest.
