Major regulator of body homeostasis
1.Hunger, thirst, sex drive, sleep-wake cycles, body temperature, blood glucose.
2.Endocrine control via release of pituitary hormones.
3.Autonomic control via descending pathways to sympathetic and parasympathetic preganglionic neurons.
4. Limbic function via connections to limbic system regulating emotional behavior. |
