How is the relationship between adenohypophysis and neurohypophysis different?

The adenohypophysis, also known as the anterior pituitary gland, produces and secretes its own hormones under the control of releasing hormones from the hypothalamus. In contrast, the neurohypophysis, or posterior pituitary gland, stores and releases hormones produced by the hypothalamus, including oxytocin and vasopressin, which are transported down axons from the hypothalamus.

Is the hypothalamic-hypophyseal tract partly contained in the infundibulum?

Yes, the hypothalamic-hypophyseal tract passes through the infundibulum, which is a funnel-shaped extension of the hypothalamus. This tract connects the hypothalamus with the posterior pituitary gland, allowing for the release of hormones such as oxytocin and vasopressin directly into the bloodstream.


Why isn't the neurohypophysis or posterior lobe of the pituitary gland a true endocrine gland?

It is only a hormone storage area that receives hormones from the hypothalamus for release. Since it does not make its own secretions (it only stores the neuroendocrine hormones made by the hypothalamus) it is not considered a true endocrine gland.
