What is a negative feedback mechanism? - Negative feedback mechanisms make up the majority of all feedback mechanisms. Negative feedback mechanism needs to be stimulated by something that has gone beyond the normal parameters to trigger a response. If a negative mechanism is triggered, the response works to reverse the action to bring the normal parameters back., What are the three components that make up a negative feedback mechanism? - The receptor, the control centre and the effector, What is a positive feedback mechanism? - Positive feedback mechanisms does the opposite to negative feedback mechanisms. Instead of reversing the stimuli, it will increase and intensify the stimuli. A good example of a positive feedback mechanism is during child birth when contractions are necessary. This is why the intensity of contractions increases depending on the progression of labour.,
