Card Set Information
Physiology is the study of function of living organisms. Physiology is the study from the molecular level to the organism level.
Any process that a living things use to maintain a fairly stable condition necessary for survival.
The maintenance of constant internal environment in response to internal/external environment.
The self adjusting mechanism involving feedback where the response to a stimulus alters the internal conditions and may itself become a new stimulus
Draw a diagram that shows the basic components of a feedback control system. Label each component.
Define Negative Feedback:
: when the response diminishes the original stimulus. negative feedback systems cannot be used to maintain stability or prevent change
Define Positive Feedback:
Is when a response enhances the original signal
Define Feedfoward Control:
Start a response loop in anticipation of a change
Define afferent limb:
Signal carried by a sensory neuron
Define efferent limb:
The electrical and chemical signals transmitted by an efferent neuron.
What is a set-point?
The acceptable range of a stimulus.
Describe why fever is NOT a breakdown in the temperature control system?
The fever temperature range is in the acceptable range of the set-point in which life can survive.
