Questions: What is the primary function of the hypothalamus? It processes auditory information. It regulates body temperature and hunger. It relays sensory information to the cerebellum. It coordinates motor movements.

The answer is the second one: it regulates body temperature and hunger.

Explanation for each option:

1. It processes auditory information.

   • Incorrect. The processing of auditory information is primarily the function of the auditory cortex, located in the temporal lobe of the brain.

2. It regulates body temperature and hunger.

   • Correct. The hypothalamus is a small region of the brain that plays a crucial role in maintaining homeostasis. It regulates various autonomic processes, including body temperature, hunger, thirst, and circadian rhythms.

3. It relays sensory information to the cerebellum.

   • Incorrect. The thalamus is primarily responsible for relaying sensory information to different parts of the brain, including the cerebellum. The hypothalamus does not perform this function.

4. It coordinates motor movements.

   • Incorrect. The coordination of motor movements is primarily the function of the cerebellum and the motor cortex. The hypothalamus is not directly involved in motor coordination.

Summary: The primary function of the hypothalamus is to regulate body temperature and hunger.
