To maintain internal stability
Homeostasis
A cycle of events in which the internal environment includes a receptor, control centre, and a effector (controlled condition)
Feedback system
Term meaning, ‘the variable being monitored’
Controlled condition
Term meaning, ‘any disruptions/changes in the controlled condition’
Stimulus
Monitors changes and sends info to control centre via transmission pathways
Sensor/Receptor
Relays messages throughout the feedback system from the nervous and blood vessel pathways
Transmission pathways
Nervous and endocrine system determines the body’s responses to the changes in the controlled condition and sets range of values to maintain
Control centre
The structure that receives commands, produces or brings about a change in the controlled condition
Effector
A stable, feedback system that functions to reverse changes in the internal environment
Negative system
A unstable, feedback system that functions to strengthen changes in the internal environment
Positive system
Term meaning the adjustment of an organism to counterbalance a defect
