Which brain structure regulates hunger, thirst, body temperature, and other basic drives?

• A. Amygdala
• B. Hippocampus
• C. Hypothalamus
• D. Cerebellum

Answer: (C)

The hypothalamus regulates hunger, thirst, body temperature, and other basic drives by acting as the body’s command center for homeostasis. It receives signals about energy status, hydration, and temperature from the body and brain, then coordinates responses through the autonomic nervous system and the pituitary gland. For hunger and satiety, different nuclei within the hypothalamus promote feeding or signal fullness, helping control energy balance. For thirst and temperature, it detects cues like osmolarity and heat and triggers behaviors (drinking) and physiological adjustments (sweating, shivering) to restore balance. This integration keeps internal conditions stable by linking neural signals with hormonal responses. Other brain regions serve different roles—emotion processing, memory, or movement coordination—rather than the broad homeostatic control described here.
