- Describe how blood sugar (e.g. glucose plasma concentration) is regulated with the hormones, insulin, and glucagon. For this feedback loop, identify the following components of the feedback loop: stimulus, receptor, control center, efferent pathway, effector, and response. Be comfortable with this feedback loop to be able to describe the effects of changing various components of the feedback loop.arrow_forwardContrast negative and positive feedback, giving one physiologic example of each mechanismarrow_forwardDescribe a general physiological control system, includingthe role of negative feedback.arrow_forward
- Select the statements that correctly describe positive feedback pathways. A sensor/receptor is required to monitor and limit levels. A sensor/receptor is unnecessary to monitor and limit levels.arrow_forwardgive two examples of feedback mechanisms in the human body. identify the type of feedback (negative or positive), the receptor, the control center and effector.arrow_forwardExplain why stabilizing mechanisms are called negative feedback.arrow_forward
- Describe the components of a negative feedback loop.arrow_forwardChoose a negative feedback loop and state the 5 components. Explain how positive feedback is different from negative feedback and give an example of positive feedback.arrow_forwardExplain the role of antagonistic effectors in maintaining homeostasis, and the nature of positive feedback loops.arrow_forward
- Select the statements that correctly describe negative feedback pathways. 1. A sensor/receptor is required to monitor and limit levels. 2. A sensor/receptor is unnecessary to monitor and limit levels. 3. Feedback contributes to homeostasis. 4. Feedback prevents homeostasis. 5. Feedback stimulates the effector to continue to do the same thing. 6. Feedback stops the effector from doing one thing and stimulates it to do the opposite. 7. When the target level for a hormone is reached, feedback results in an increase of that hormone being released. 8. When the target level for a hormone is reached, feedback results in a reduction of that hormone being released. Record your answers in ascending (lowest to highest) order.arrow_forwardThe role of insulin is to signal the cells to uptake glucose from the blood. Is this a positive or negative feedback loop? Explain what would happen if the other type of feedback loop were to occur.arrow_forwardDefine the term negative feedback loop and positive feedback loop and explain how they differ from each other.arrow_forward
