Explanation The embryonic origin of the neurohypophysis (posterior pituitary lobe) is the infundibulum which is a down growth of the brain. The neurohypophysis stores two hormones- oxytocin and vasopressin that are also known as antidiuretic hormones (ADH) secreted by the hypothalamus. It releases these hormones upon the stimulation from the hypothalamus and it is controlled by neuroendocrine reflexes...

Summary Introduction

To review:

The relation between the regulation of the neurohypophysis and adrenal medulla with their embryonic origins.

Introduction:

The pituitary gland, also known by the term hypophysis, is a small pea-sized gland present in the brain and it is divided into two lobes namely- the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis). It is the neural part of the pituitary gland. The adrenal gland is located at the top of the kidneys and contains two parts- the adrenal cortex and the adrenal medulla.
