Surface structure of the cellular elements of the pigeon crista ampullaris was studied using a scanning electron microscope. The vertical and the lateral cristae ampullares were markedly different from each other mostly due to the presence of two prominent humps in the middle of the vertical cristae, the eminentia cruciata.
Studied were the hair cells on the cristae, three types of cells on the eminentia cruciata, two types on the slope of the cristae, two types on the planum semilunatum and those on the ampullary wall.
