It regulates blood pressure (BP), heart rate, sleep, glandular, pupillary, bladder and bowel function. It maintains organ homeostasis and operates automatically; its full importance becomes recognized only when ANS function is compromised, resulting in dysautonomia. Hypothalamic disorders that cause disturbances in homeostasis are discussed in Chaps. 15 and 371.
