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.
