What are the 2 hormones stored in the Posterior Pituitary?

Solutions

Expert Solution

The posterior pituitary stores two hormones secreted by the hypothalamus for later release:

Oxytocin, most of which is released from the paraventricular nucleus in the hypothalamus. ...
Antidiuretic hormone (ADH, also known as vasopressin), the majority of which is released from the supraoptic nucleus in the hypothalamus.

The posterior pituitary secretes two important endocrine hormones—oxytocin and antidiuretic hormone.

The posterior pituitary (or neurohypophysis) comprises the posterior lobe of the pituitary gland and is part of the endocrine system.
Hormones known as posterior pituitary hormones are synthesized by the hypothalamus, and include oxytocin and antidiuretic hormone.
The hormones are then stored in neurosecretory vesicles (Herring bodies) before being secreted by the posterior pituitary into the bloodstream.

oxytocin: A hormone that stimulates contractions during labor.
posterior pituitary: The posterior pituitary (or neurohypophysis) comprises the posterior lobe of the pituitary gland and is part of the endocrine system. Despite its name, the posterior pituitary gland is not a true gland; rather, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary gland.
Antidiuretic hormone: A hormone that stimulates water re-absorption in the kidneys.

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.
