Question

Injury localized to the hypothalamus would most likely disrupt

• A. short - term memory
• B. co-ordination during locomotion
• C. executive functions, such as decision making
• D. regulation of body temperature.

Answer 1

The Correct Option is D

To determine which function would most likely be disrupted by an injury localized to the hypothalamus, let's explore the role of the hypothalamus in the human brain:

• Hypothalamus Function: The hypothalamus is a small but crucial part of the brain located below the thalamus. It plays a significant role in regulating bodily functions such as hunger, thirst, sleep, emotional activity, and, importantly, body temperature.
• Body Temperature Regulation: The hypothalamus contains thermoreceptors that detect changes in blood temperature. It initiates responses to temperature changes, such as sweating or shivering, to maintain homeostasis. Thus, it's primarily responsible for regulating body temperature.
• Other Functions Considered:
  • Short-term memory: This is primarily associated with the hippocampus, not the hypothalamus.
  • Coordination during locomotion: This function is largely controlled by the cerebellum.
  • Executive functions (e.g., decision making): Such functions are generally attributed to the prefrontal cortex of the brain.

Given these roles and functions, injury to the hypothalamus is most likely to disrupt the regulation of body temperature. Other options pertain to functions governed by different parts of the brain.

Conclusion: The correct answer is regulation of body temperature.
