What is the main function of a receptor in a homeostatic system?
Detecting changes in a variable or stimulus
Which component of a homeostatic system initiates changes through effectors?
Control center
In the context of homeostasis, what is the primary function of an effector?
Bringing about changes to alter the stimulus

Activities requiring rapid responses
Which component of a homeostatic system detects a change in a variable?
Receptor
What is the purpose of a negative feedback loop in a homeostatic system?
To maintain or return the variable to homeostasis
Which of the following factors is NOT homeostatically regulated?
Room temperature
What is the role of effectors in a homeostatic system?
Initiate changes in response to stimuli
In a homeostatic system, where is the information integrated to initiate a response?
Control center
Which type of feedback loop involves intensifying the original stimulus?
Positive feedback loop
What type of system maintains the variable within a normal range?
Homeostatic control system
In a negative feedback system, when the stimulus decreases, what action is taken by the homeostatic control system?

What is the role of the hypothalamus in temperature regulation within a negative feedback system?
Alerts nerve impulses to increase blood flow to the skin
How does the body respond when sensory receptors detect a drop in body temperature in a negative feedback system?
Activate shivering and 'goosebumps'
What is the primary function of negative feedback systems in maintaining homeostasis?
To keep variables constant and unchanging
In a negative feedback system, what happens if the stimulus increases?
Homeostatic control system causes a decrease in the stimulus
