The posterior pituitary, also known as the neurohypophysis, is responsible for the storage and release of specific hormones that are produced in the hypothalamus. One of the key hormones secreted by the posterior pituitary is anti-diuretic hormone (ADH), also known as vasopressin.

ADH plays a critical role in regulating water balance in the body by promoting water reabsorption in the kidneys. This helps to concentrate urine and maintain blood pressure. When the body is dehydrated or when blood volume is low, the hypothalamus signals the posterior pituitary to release ADH into the bloodstream, which then acts on the kidneys to conserve water.

In contrast, other hormones listed, such as thyroid-stimulating hormone, adrenocorticotropic hormone, and growth hormone, are produced in the anterior pituitary or other glands and are not secreted by the posterior pituitary. Understanding the distinct roles of various hormones and their origins is essential for grasping the complexities of the endocrine system.
