What feedback reverses a change in the body’s physiological condition so the system returns to the normal range?

Question

BlackTom AI · Accepted Answer

The question asks which type of feedback reverses a change in the body’s physiological condition so the system returns to the normal range.
Option a: Autocrine. Autocrine signaling involves a cell releasing substances that act on the same cell that released them. This is a local signaling mechanism, not a feedback process that reverses a physiological deviation, so it does not fit the description.
Option b: Biofeedback. Biofeedback is a technique where individuals learn to control physiological processes by receiving real-time feedback from their body (e.g., heart rate, skin temperature). While it involves feedback concepts, it is a self-regulation method rather than the natural homeostatic feedback mechanism that reverses a change in the set point, so it is not the standard term described.
Option c: Negative. Negative feedback is the classic mechanism that detects a deviation from a set point and initiates responses to counteract that change, thereby restoring the normal range. This directly matches the described function of reversing a physiological change.
Option d: Positive. Positive feedback amplifies a deviation rather than reversing it, driving processes away from the set point (e.g., blood clotting, uterine contractions during birth), so it does not fit the description.
Option e: Feedforward. Feedforward anticipates changes and acts to prevent deviation before it occurs, rather than reversing a change once it has happened. While useful, it is not the mechanism that reverses an existing deviation to restore normal range.
