Question

The origin of adenohypophsis is?

Answer 1

hey dear sweet friend here is your answer

The posterior part of the pituitary has its embryological origins in nervous tissue. It is formed from a downgrowth of the diencephalon that forms the floor of the third ventricle. The anterior part is derived from an upgrowth from the oral ectoderm of the primitive oral cavity called Rathke's pouch.

hope it's help

Answer 2

Hi mate

The anterior lobe (adenohypophysis) is derived from oral ectoderm and is epithelial in origin, whereas the posterior lobe (neurohypophysis) derives from the neural ectoderm. The composite nature of the pituitary requires that the neural and oral ectoderm interact physically and developmentally.
