Briefly explain negative feedback in homeostasis and one common misconception about it.

## Negative Feedback in Homeostasis **Negative feedback** is a regulatory mechanism where a change in a physiological variable triggers a response that counteracts the initial change, returning the system to its set point (normal range). **How it works:** 1. A sensor detects a deviation from the set point 2. A control center processes this information 3. Effectors produce a response that reverses the deviation **Example:** When body temperature rises, thermoreceptors signal the brain, which triggers sweating and vasodilation to cool the body back down. ## Common Misconception Many people think "negative" means harmful or bad, but **negative feedback is actually stabilizing and beneficial**. The term "negative" simply means the response opposes or negates the initial change—it's about reversing direction, not about being detrimental. In fact, negative feedback maintains the stable conditions necessary for survival.
