The hypothalamus regulates emotional responses through its influence on the pituitary gland, skeletal muscular system, and autonomic nervous system. Hypothalamus: Function. The hypothalamus is involved in several functions of the body including: Autonomic Function Control; Endocrine Function Control; Homeostasis; Motor Function Control
This is called maintaining homeostasis. The hypothalamus also maintains homeostasis in lots of other ways, such as by controlling your blood pressure. The hypothalamus also controls many of your hormones. It does this by being a sort of gatekeeper for other glands that release hormones. When your hypothalamus senses a change in your body, it will tell the right gland how to help correct that change.
