| Abstract: | The pineal glands obtained from two human fetuses were studied morphologically. Light microscopic examinations revealed its structure as an organ consisting of tall or cuboidal cells with a lumen at the center. The most striking finding was obtained through electron microscopic observation, which was cilia formation by the pinealocyte. The cilium was seen quite often, definitely of 9+0 pattern, associated by satellite bodies and rootlet structure. These features are considerably different from those in the human adult but quite similar to those of some species of lower animals, which would also endorse the sensory nerve origin of the pineal glands in man.
