Explain the concept of negative feedback and how it helps to maintain
homeostasis. - Correct-answer-1- The effect or increased level of the hormone
acts to shut down the con!nued release of the hormone. 2- The brain is
constantly monitoring hormone levels to keep levels within a certain range or set-
point (homeostasis). Nega!ve feedback is a way of "turning off" hormone
produc!on when the desired level is achieved
4. Explain the concept of positive feedback. Give an example of a hormone
that works through positive feedback. - Correct-answer-1- Positive feedback is
the action of a hormone increasing the production of that hormone. (This is the
opposite of negative feedback). 2- One example is the action of oxytocin causing
the uterus to contract during labor. Oxytocin enhances the effect of the uterus
contractions, causing more oxytocin to be released. The positive feedback loop is
stopped once the baby is born and the uterus no longer needs to contract,
stopping the production of oxytocin.
