Un fenomeno similar acontece con las dos porciones de la hipofisis: Adenohypophysis y Neurohypophysis, pues el primer termino utiliza la particula adeno que en griego significa glandula, para denominar a la porcion anterior de la hipofisis que fisiologicamente participa del control hormonal; el segundo termino, por su parte, utiliza la particula neuro, que en griego significa nervio, para denominar a la porcion posterior de la hipofisis que constituye parte del sistema nervioso.
