WebAug 5, 2024 · A positive feedback loop in the endocrine system is more rare, happening for only some hormones. A positive feedback loop in the endocrine system is when release of a hormone initiates actions that lead to an additional release of that hormone. Unlike a negative feedback loop, a positive one is not looking to reach homeostasis (stability). WebPositive feedback loops actually push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine system of mammals. Negative Feedback Mechanisms. Any homeostatic process that changes the direction of the stimulus is a negative feedback loop.
