Can someone please explain to me how both negative and postive feedback control hormone release?

and give an example of each.





Thanks :-)Can someone please explain to me how both negative and postive feedback control hormone release?
Any system, whether it is an open or closed, that regulates its internal environment to establish a stable and constant condition is said to be controlled by homeostasis. So the control of hormone levels is controlled by homeostasis, the levels are controlled in one of two way’s the first being controlling the release of the hormone and the second is by “mopping up” excess hormones.





A positive feedback mechanism is designed to accelerate or enhance the output created by a stimulus that has already been activated. To achieve positive feedback a series of events initiates a cascading process that builds to increase the effect of the stimulus. This process can be beneficial but is rarely used by the body due to risks of the acceleration becoming uncontrollable. An example of positive feedback is the release of oxytocin to intensify the contractions that take place during childbirth.





Negative feedback mechanism consists of reducing the output or activity of any organ or system back to its normal range of functioning. An example of negative feed back is the way mammals regulate their blood glucose with insulin and glucagon.





Hope this is of some help.
