Examples of positive and negative feedback mechanisms involving endocrine hormones? |
|
Answer» positive FEEDBACK - ENHANCES the EFFECT by its own influence. for example - oxytocin produced during childbirth stimulates contraction. the CONTRACTIONS in turn stimulate pituitary to produce more oxytocin, thus bringing about more contractions. negative feedback - counteraction of an effect by its own influence. for example insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low |
