What is the other hormone released from the posterior lobe of the pituitary besides Oxytocin?

The hormone released from the posterior lobe of the pituitary gland, in addition to oxytocin, is Antidiuretic Hormone (ADH), also known as vasopressin. The posterior pituitary does not produce hormones itself; instead, it stores and releases hormones that are produced in the hypothalamus. ADH plays a crucial role in regulating water balance in the body by promoting water reabsorption in the kidneys. When ADH levels rise, the kidneys reabsorb more water, reducing urine output and concentrating the urine, which helps to maintain blood pressure and fluid balance.

In contrast, insulin is produced by the pancreas and is crucial for glucose metabolism, while cortisol is a steroid hormone produced by the adrenal glands that helps manage stress and metabolism. Growth hormone, produced by the anterior pituitary, plays a significant role in growth, metabolism, and body composition but is not involved in the functions of the posterior lobe.
