Explain the concept of negative feedback and how it helps to maintain homeostasis.


✓ -:- 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.


✓ -:- 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.
