|
Is some type of sensor that monitors the environment ans responds to changes
|
receptor
|
|
determines the set point ,anayles the input it recieveds and then determines the apporiate response and course of action

|
|
provides the means for the control centers response to the stimilus
|
effector
|
|
shuts off the original stimilus or reduces the intensity
|

|
|
examples of negative feedback
|
regulation of body temp
withdrawal reflex (hand jerked away from painfil stimilus) control of blood glucose levels |
