Posterior pituitary gland is the back portion of the pituitary. It is a small gland in the head called the master gland. It does not synthesize any hormone but stores and releases two hormones ADH (Antidiuretic Hormone) and Oxytocin.
Antidiuretic hormone is released in response to a fall in the water content of blood plasma and leads to an increase in the permeability to water of the distal and collective tubules of the nephron in the kidney so that water is retained in the blood plasma.
