Let me share with you a comparison between Positive Feedback and Negative Feedback Mechanism.
| Aspect | Positive Feedback mechanism | Negative Feedback mechanism |
| Introduction | A process in which the response intensifies the original stimulus, promoting a self-amplifying cycle. | A process in which the stimulus amplifies the changes rather than reversing it. |
| Regulation Type | Rare and often associated with processes that require rapid and decisive responses. | Common and predominant in maintaining stable internal conditions. |
| Stability | Can lead to instability | Promotes stability |
| Set Point Adjustment | Usually doesn’t involve setting a new set point | Helps bring the system back to the original set point. |
| Examples
|
· During blood clotting, platelet release signals for more platelets to aggregate, amplifying the clotting process.
· Oxytocin release during childbirth contractions · Surge in luteinizing hormone (LH) during the menstrual cycle.
|
· Sweating in response to high body temperature cools the body.
· Insulin release in response to high blood glucose · Release of cortisol in response to stress.
