Similarly, it is asked, what is an example of positive feedback in the endocrine system?
Unlike negative feedback that maintains hormone levels within narrow ranges, positive feedback is rarely used to maintain homeostatic functions. An example of positive feedback can be found in childbirth. The hormone oxytocin stimulates and enhances labor contractions.
One may also ask, what is an example of a positive feedback mechanism? In a positive feedback system, the output enhances the original stimulus. A good example of a positive feedback system is child birth. During labor, a hormone called oxytocin is released that intensifies and speeds up contractions. Another good example of a positive feedback mechanism is blood clotting.
Correspondingly, what are the two main mechanisms by which hormones work?
There are two major mechanisms, second-messenger mechanisms and direct gene activation, by which the hormone activates the target cell. Direct Gene Activation. Steroid hormones pass through plasma membrane (they're lipid soluble) and attach to receptor molecules that are inside the cell.
Is breastfeeding positive or negative feedback?
Feedback control may be positive or negative. There are very few positive feedback systems in the body. One example, however, is lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation.
