A change, either an
increase or decrease in the
level of an internal variable.
(Sensory neuron)
The
structure
that
detects the
change
and sends
signals to
the effector
(Motor neuron)
The structure
that adjusts its
output to make
the required
correction
The structure that evaluates the change and
sends signals to the effector
The corrective
action taken
(increase or
decrease in
variable)
The counteracting effect
of the response on the
stimulus.
