Detailed explanation-1: -Neurosecretory cells in the hypothalamus release oxytocin (OT) or ADH into the posterior lobe of the pituitary gland. These hormones are stored or released into the blood via the capillary plexus.
Detailed explanation-2: -ADH, also known as arginine vasopressin, is a hormone produced by the hypothalamus and stored in the posterior pituitary gland. It is made up of special nerve cells found at the base of the hypothalamus. The hormone is transported to the pituitary gland via axons, where it is released into the bloodstream.
Detailed explanation-3: -The hypothalamus secretes hormones that stimulate or suppress the release of hormones in the pituitary gland, in addition to controlling water balance, sleep, temperature, appetite, and blood pressure.
Detailed explanation-4: -What is oxytocin? Oxytocin is produced in the hypothalamus and is secreted into the bloodstream by the posterior pituitary gland. Secretion depends on electrical activity of neurons in the hypothalamus – it is released into the blood when these cells are excited.
