since the latency is due predominantly to conduction in the first order axon , and since there is a direct linear relation between conduction velocity and fiber diameter in the medullated nerve fibers , it is possible to speculate that the regular cells have thin fibers which innervate the slope of the crista , the irregular neurons have thick fibers which innervate the summit of the crista , and the intermediate units have medium caliber fibers which innervate both the slope and summit of the crista ampullaris .
