All Homeostatic control mechanisms have at least three independent components these consist of a receptor, controller and effector. A receptors job is to detect the change in this case of blood glucose levels and alert the control center (controllers) to act on this change and return the body back to its set point of 5mmol, a receptor measures a variable. A controller receives the impulses from the receptor, the information that is received from the receptor is then compared to the body’s set point, it sends commands to the effector, and an Effector acts on the impulse sent by the control center. This then makes a change to the system to negate the effect of the input and the response is it gets the body back to the set point and returning …show more content…
The reason it is called a negative feedback system is that it is opposing the change that deviates from the normal/set point. There are receptors, controllers and effectors that all play a part in glucoregulation. There are different receptors, controllers and effectors that all work together to control high blood glucose and to return it back to its set point. The stimulus for high blood glucose is the blood glucose level if it higher than the set point of 5mmol. The receptors are beta cells they release insulin in to the blood, the controllers are the beta cells again they send a hormone message out and the effector is the liver, muscle cells and fat cells and pancreas these all work together to lower the body’s blood glucose and return the body back to its set point. There are also receptors, controllers and effectors that work together to get the body back to its set point if the level of blood glucose gets to low, which is very
