Which part of the brain plays a key role in maintaining homeostasis by regulating body temperature, hunger, thirst, and endocrine function?

• A. Medulla oblongata
• B. Hypothalamus
• C. Cerebellum
• D. Hippocampus

Answer: (B)

Verified step by step guidance

1. Understand that homeostasis refers to the body's ability to maintain a stable internal environment despite external changes.
2. Identify the brain regions listed: Medulla oblongata, Hypothalamus, Cerebellum, and Hippocampus, and recall their primary functions.
3. Recall that the Medulla oblongata controls autonomic functions like breathing and heart rate, but not temperature or hunger regulation.
4. Recognize that the Hypothalamus is responsible for regulating body temperature, hunger, thirst, and endocrine functions, making it central to homeostasis.
5. Confirm that the Cerebellum is mainly involved in motor control and the Hippocampus in memory formation, so they are not primarily involved in homeostasis.
