# Hypothalamus - tiny area of the [[Brain]] - extends its influence to nearly every organ of the body. - Controls the [[autonomic nervous system]] (which is responsible for such vital functions as [[heart rate]] and [[blood pressure]]) - Contains centres responsible for [[hunger]], [[thirst]], and [[temperature regulation]] - Controls the [[pituitary gland]]—often called the “master gland” because of its influence on most endocrine glands (such as the [[thyroid]], [[testes]], [[ovaries]], and [[adrenal glands]]) - Is involved in multiple emotional responses, including [[fear]], [[anger]], [[pleasure]], and [[aggression]] - VERY responsive to [[mood]] and [[stress]] - therefore [[stress management]] is vital for [[hormonal balance]] - Governor of the [[endocrine system]] - [[hormones released by the hypothalamus]]
