Stimulus Response Negative Feedback Example

A stimulus can be internal or external.

Stimulus response negative feedback example. The thermostat is a prime example of negative feedback and we see the same thing happen in the biochemistry of living things. Remember to personalize each review response and avoid canned responses. A negative feedback loop is a reaction that causes a decrease in function.

Stimulus response stimulus something that can elicit or evoke a response in a cell a tissue or an organism. This can be referred to as homeostasis as in biology or equilibrium as in mechanics. Often it causes the output of a system to be lessened.

In turn the pathway is eventually shut off. It occurs in response to some kind of stimulus. Remember that feedback mechanisms can be a part of systems of all sizes from chemical pathways to the activities of entire groups of organisms.

The diagram below helps to explain this using the example of body temperature. In this case the effector the secreting cells would be adjusted downward. The body will do this by opposing a change that deviates from the normal.

The stimulus produces a reaction in the bees which lowers the stimulus. Therefore using temperature change as a stimulus in humans we can show this type of feedback. A negative feedback system directly affects its stimulus.

For example negative feedback loops involving insulin and glucagon help to keep blood glucose levels within a narrow concentration range. A negative feed back response is one in which bring the body back to normal homeostasis. Stimulus sensor control center and effector.
