Hypothalamus Homeostatic Control

The hypothalamus is a small region of the brain that plays a crucial role in homeostatic control by regulating various physiological processes, including temperature, hunger, thirst, and circadian rhythms, through the release of hormones and the activation of the autonomic nervous system. It acts as a central coordinator, integrating signals from the body to maintain internal balance and respond to changes in the environment.
