The hypothalamus is a small but crucial brain region linking the nervous and endocrine systems, acting as the body’s control center for maintaining homeostasis (internal balance) by regulating temperature, hunger, thirst, sleep, mood, stress, and hormone release via the pituitary gland. It receives signals from the body and brain, coordinating essential functions like body temperature, appetite, sleep cycles, blood pressure, and emotional responses, making it vital for survival.
