what are the two type of control systems? - Answer local and reflex
what is local control systems? - Answer restricted to local area of the body
what is the reflex control systems? - Answer Widespread throughout the body
,What order do these steps happen?
integrating center, output signal, input signal and response - Answer - input signal
- integrating center
- output signal
- response
what does local control do? - Answer turns active cells to reduced O2 levels in tissue.
what cells send local signals in local control? - Answer Endothelial cells
what is the result from local control? - Answer - causes smooth muscle to relax
and allow more oxygen to capillary
- O2 levels in tissue restored
what does reflex control refer to? - Answer any long distance pathway that uses
the nervous, endocrine system or both
what do reflex control uses in its process? - Answer - uses long-distance signaling
What is to maintain homeostasis in reflex control? - Answer - more complex control
systems
- changes widespread throughout the body use more complex control systems
to maintain homeostasis
,what two parts in the reflex control broken down into? - Answer - the response
loop - the feedback loop
what is the response loop? - Answer When some kind of change is detected
What is the feedback loop? - Answer - modulates the response loop
- feeds back to ultimately influence the input
what is the order of these steps in the reflex control?
sensor, integrating center, response, stimulus, output signal, target, input signal -
Answer - Stimulus
- sensor
- input signal
- integrating center
- output signal
- target
- response
what are some examples of when reflex control is antagonistic (showing or feeling
active opposition or hostility toward someone or something)? - Answer - heater and
air conditioner
- in the body dual control of heart rate
What does it mean when the function to maintain homeostasis is local? - Answer it is
restricted to a small region of the body
, what does it mean when the function to maintain homeostasis is reflex? - Answer - it is
systemic (wide spread throughout the body)
- usually involve the nervous and/or endocrine systems (negative feedback,
positive feedback, feedforward)
what are negative feedback loops? - Answer a pathway in which the response opposes
or removes the stimulus signal is known as negative feedback
what does the negative feedback loop do? - Answer - stabilizes a system
- can restore the initial state but cannot prevent the initial disturbance
is the negative feedback loop homeostatic? - Answer yes
