nervous system

what system responds fastest to environmental stimuli?

positive feedback

when a baby suckles at its mother's breast the stimulus at the breast is sent to the mother's brain (a region called the hypothalamus). the brain responds by releasing hormones to stimulate the production and the ejection of milk from the breast. this helps the newborn to receive nourishment and encourages more suckling. this example is best described as a ____
