Morphology and electrophysiological properties of cutaneous sensilla in agamid lizards.

The external morphology of agamid cutaneous sensilla has been studied by means of the scanning electron microscope (SEM). Electrophysiological recordings from single organs were obtained in response to mechanical bending of the centrally located long seta. In this way the mechanoreceptive function of reptilian cutaneous sensilla has been established for the first time.
