Homeostatic Control Systems - Homeostatic Control Mechanisms and Feedback Control Loops

All organs and systems in the body are working to maintain homeostasis

• True

• False

How does the body change its internal environment when necessary?

• homeostatic control mechanisms

• homeostatic switches

• homeostatic changes

What are two ways feedback control loops transmit information?

• Through nerve impulses and blood pressure

• Through nerve impulses and hormones

• Through hormones and muscle spasms

What is another name that we used in class that can be used for the sensor mechanism, the part that detects a change?

• Integrator

• Receptor

• Signal

What organ is often the control center of a feedback control loop?

• heart

• liver

• brain

The effector mechanism is the third part of the control mechanism.  What is the job of the effector mechanism?

• To provide the response desired

• To send a signal to the brain

• To change the set point value for the entire system

What is the receptor (sensor) for the human?

• A thermometer

• Temperature receptors in the skin

• The blood

• The heart

What is the integrator/control center for the house?

• The brain

• The roof

• The furnace

• The thermostat

What is the effector for the human?

• The furnace

• The muscles

• The brain

• The nerves

Homeostasis is best defined as 

• the body's ability to maintain a stable internal environment

• the body's ability to change

• the body's ability to relate to the environment
