Answer;
- Sensory Receptors: Detects changes of internal or external stimulus.
- Integrating center: sends signals to proper areas of the body regarding the stimulus.
- Effectors: Respond to stimulus to maintain homeostasis.
Step-by-step explanation;
-A receptor is the structure that monitors internal and external conditions . Receptors sense changes in function and initiate the body's homeostatic response. These receptors are connected to a control center that integrates the information fed to it by the receptors. In most homeostatic mechanisms, the control center is the brain.
-When the brain receives information about a change or deviation in the body's internal conditions, it sends out signals along nerves. These signals prompt the changes in function that correct the deviation and bring the internal conditions back to the normal range.
-Effectors are muscles, organs, or other structures that receive signals from the brain or control center. When an effector receives a signal from the brain, it changes its function in order to correct the deviation.
