Final answer:
In negative feedback regulation, the effector mechanisms are responsible for maintaining homeostasis by counteracting physiological deviations and returning the body to a normal range, such as in body temperature regulation.
Step-by-step explanation:
In negative feedback aspects of internal physiological environment are regulated by antagonistic effector mechanisms. Negative feedback is a crucial biological process that helps maintain homeostasis in an organism's internal environment. When a physiological value deviates from the normal range, a sensor detects this change and relays the information to the control center, which then activates an effector. The effector's role is to counteract the deviation and bring the value back to the normal range, thereby maintaining homeostasis. An example of this can be seen in body temperature regulation, where a rise in body temperature triggers the sweat glands to cool the body down, and once the temperature is normal, the sweating stops. This is an illustration of a negative feedback loop.
