Term
|
Definition
| the study of processes that go on in our body, from the cellular level to the organ system level that contribute to maintaining a relatively stable internal environment. |

Term
|
Definition
| specific variable which is being monitored. |
|
|
Term
|
Definition
| target value at which we desire to keep the regulated variable |
|
|
Term
|
Definition
| monitor the variables (chemoreceptors, pressure receptors, thermoreceptors, etc.) |
|
|
Term
|
Definition
| route by which information collected by the sensors is transmitted to the integrating center |
|
|
Term
|
Definition
| the difference between the actual value as measured by sensors and the desired set point |
|
|
Term
|
Definition
| receives information from the sensors and compares it to the desired set point. If these values do not match (error signal), then the integrating center sets into motion necessary changes to bring the regulated variable back toward the set point. |
|
|
Term
|
Definition
| route by which information from the integrating center is sent out to the effectors |
|
|
Term
|
Definition
| mechanisms which can be called upon to bring about change in the variable being monitored |
|
|
Term
|
Definition
| information that is "fed back" into the system. This is a mechanism to dynamically control the magnitude of a response. |
