Positive feedback and homeostasis Complete the following paragraph to describe how positive feedback helps maintain homeostasis. Choices may be used more than once. A homeostatic mechanism that brings about changes in the direction is called positive feedback. For example, when a woman is giving birth, contractions cause the baby's head to press against the cervix, activating the The activates nerve impulses that reach the in the brain, which in turn, releases oxytocin, causing further contractions. In this mancor positive feedback results in a(n) in mulus, whereas negative feedback results in a(n) in the initial stimulus. 7) in the increase decrease control center same opposite sensor
