In negative feedback, the role of effectors is to counteract the changes or disruptions that occur in the body's internal environment. Effectors are usually muscles or glands that respond to signals from the control center, which is often the brain or a specific endocrine gland.
Once the control center detects a deviation from the desired set point, it sends signals to the effectors in order to restore balance. The effectors work to oppose or reverse the initial change that triggered the feedback loop.
For example, if body temperature rises above the set point, the control center (hypothalamus) activates effectors such as sweat glands and blood vessels in the skin. Sweat glands produce sweat, which helps cool down the body as it evaporates from the skin's surface. The blood vessels dilate, allowing more blood to flow to the skin surface, which also aids in heat dissipation.
Similarly, in response to low blood sugar levels, the control center (pancreas) releases hormones that stimulate the liver to convert stored glycogen into glucose. This glucose is then released into the bloodstream, helping to raise blood sugar levels back to the set point.
Overall, the role of effectors in negative feedback is to bring the body back to a state of homeostasis by counteracting the initial disturbance.
