| description | aberrant formation or incomplete differentiation of the posterior lobe of the pituitary gland which develops as a neurohypophyseal bud, a depression in the neuroectoderm of the floor of the hypothalamus; the infundibulum, another diverticulum from the inferior aspect of the diencephalon, develops as an outgrowth of the neurohypophyseal bud and connects the neurohypophysis to the hypothalamus; the neurohypophysis develops as the infundibulum grows inferiorly from the diencephalon to meet the developing adenohypophysis (anterior pituitary lobe); the fully developed neurohypophysis consists of the infundibulum and the pars nervosa; the neural connection between the hypothalamus and pars nervosa is through the hypothalamohypophyseal tract that develops within the infundibulum |
