Question
Chapter 1, Problem 9CP
Summary Introduction
To review:
The types of disturbances that can act as stimuli that initiate a feedback system.
Introduction:
A feedback system is formed by communication of group of receptors and effectors with their respective control center, which in turn, regulate a controlled condition in the body's internal environment.

What is the role of subtle mechanisms?
Organismal homeostasis depends upon the presence of control systems. Give a physiological example of a negative feedback control system its positive feedback. Clearly describe the role(s) that each of the following elements plays in all control systems: such as controller, effector and receptor.
Define homeostasis. What happens when homeostasis fails?
List the three basic components of a control system and give an example.
Describe the components of a reflex pathway. Contrast the response loop and the feedback loop.
Explain the relationship between a regulated physiological variable and its setpoint. Is the physiological variable
exactly at its setpoint?
Compare and contrast negative and positive feedback. Give a biological example of each.
Is the setpoint constant or can it change over time? If setpoints can change over time, what is this called?
