_____ feedback stimulates your body to respond in the same direction as a stimulus. negative positive
Yes they do respond to stimulation-by sun light-they respond  the same as flowers do by bending and shifting their leaves toward  the sun. The amount of movement is some … what less noticeable than  the bending of a flower but it is there. Which of the following hormones is released by the corpus luteum after ovulation and causes a negative feedback loop with the hypothalamus and the anterior pituitary? Positive feedback is a process that occurs in a feedback loop in which the effects of a small disturbance on a system include an increase in the magnitude of the perturbation. That is, A produces more of B which in turn produces more of A. You must be a registered user to view the premium content in this website. If you already have a username and password, enter it below.

This is because positive feedback stimulates your body to respond in the same direction as the stimulus, most often increasing instability. 1 Lactation also involves positive feedback in that as the baby suckles on the nipple there is a nerve response into the spinal cord and up into the hypothalamus of the brain, which then stimulates the pituitary gland to produce more prolactin to produce more milk. The result of positive feedback is to augment changes, so that small perturbations may result in big changes. A system in equilibrium in which there is positive feedback to any change from its current state may be unstable, in which case the equilibrium is said to be in an unstable equilibrium. 4. A positive feedback loop causes a self-amplifying cycle where a physiological change leads to even greater change in the same direction. True. False. 5. A negative feedback loop is a process in which the body senses a change, and activates mechanisms to reverse that change. Positive feedback loops rarely occur. This is because positive feedback stimulates your body to respond in the same direction as the stimulus, most often increasing instabilit … y. Positive feedback enhances or amplifies an effect by it having an influence on the process which gave rise to it. For example, when part of an electronic output signal returns to the input, and is in phase with it, the system gain is increased.
