The hypophysis is unit formed by the pituitary and the hypothalamus. These two glands are connected by the blood flow in what system?

a. Hypophyseal portal system

b. Supraoptic portal system

c. Paraventricular portal system

d. Hypothalamic portal system

Expert Solution

Here, the right option is Option A

Hypophyseal portal system is the connection between pituitary gland and hypothalamus by which there will be transportation and exchange of blood takes places. This type of portal system is made up of the tiny blood vessels of both pituitary and hypothalamus.

Portal system is a type of communication between the blood vessels of different organs.It can develop in any organ. So here, the communication of blood vessel is existing between pituitary gland and hypothalamus. This connection of blood vessels help's in exchanging the hormones and blood between pituitary and hypothalamus.

There is no other portal system such as supra optic portal system paraventricular portal system, and hypothalamic portal system etc.Hence all those options can be excluded here.The major hormones exchanged here are the releasing hormones secreted by the hypothalamus such as Thyrotropin Releasing Hormones, Growth hormone releasing hormone corticotropin releasing hormones etc.

Draw a diagram of the hypothalamus and its connection to the posterior pituitary (2). Include ONLY the neurosecretory cells that secrete an antidiuretic hormone (ADH). The cells that secrete ADH are osmoreceptors that respond to high blood osmolarity by secreting ADH. Given the information about the target organ and action of ADH, explain the homeostatic mechanism that involves ADH that acts when blood osmolarity is too high and be sure to explain how the original stimulus is reversed.

The hypothalamus-pituitary complex can be considered as the master control center for the endocrine system. Contrast how the hypothalamus communicates differently with the anterior pituitary gland compared to the posterior pituitary gland. Using a specific example, describe the process by which the hypothalamus can direct the secretion of an anterior pituitary gland hormone and the effects at the target organ or tissue.
