GENERAL HISTOLOGY

Detailed explanation-1: -The neurohypophysis (pars posterior) is a structure that is located at the base of the brain and is the posterior lobe of the pituitary gland. Its embryological origin is from the neuroectodermal layer called the infundibulum . The neurohypophysis is divided into two regions; the pars nervosa and the infundibular stalk.

Detailed explanation-2: -The neurohypophysis consists of three parts: the supraoptic and paraventricular nuclei of the hypothalamus; the supraoptico-hypophyseal tract; and the posterior pituitary.

Detailed explanation-3: -The posterior pituitary is often termed the neurohypophysis because the hormones of this part of the pituitary are released directly from the axonal endings of their source neurons into the circulation (Figure 2.1).

Detailed explanation-4: -Neurohypophysis is the center for the hormonal secretion of oxytocin and vasopressin.
