physiology & homeostasis Flashcards
1
Q
feedforward
A
used for responses made in anticipation of a change
2
Q
feedback
A
Refers to responses made after change has been detected
3
Q
positive feedback
A
amplifies an initial change
4
Q
negative feedback
A
opposes an initial change - main type of physiological control mechanisms
5
Q
to maintain homeostasis - what must negative feedback control be able to do?
A
- Sense deviations (Sensor) from desired range in a Regulated Variable that needs to be kept within a narrow range (Set Point)
- Integrate this information with other relevant information (Control Centre)
- Make appropriate adjustments (Effector(s)) in order to restore regulated variable to its desired range (set point)
