Emotions influence autonomic reactions primarily through integration in the:

• A. cerebellum
• B. hypothalamus
• C. parietal cortex
• D. occipital lobe

Answer: (B)

Verified step by step guidance

1. Understand that emotions influence autonomic reactions by affecting the body's involuntary functions such as heart rate, respiration, and digestion.
2. Recall that the autonomic nervous system is regulated by brain structures involved in homeostasis and emotional processing.
3. Identify the brain regions listed: cerebellum (motor control), parietal cortex (sensory processing), occipital lobe (visual processing), and hypothalamus (regulation of autonomic functions).
4. Recognize that the hypothalamus plays a central role in integrating emotional signals and coordinating autonomic responses to maintain internal balance.
5. Conclude that the hypothalamus is the primary brain structure through which emotions influence autonomic reactions.
