what's the receptor - (ANSWER)body structure monitoring the changes of a controlled condition and
sends inputs
what is an afferent pathway-input - (ANSWER)flows towards the control center (nerve impulse or
chemical signal)
what is the control center - (ANSWER)sets the range of values within which a controlled condition should
be maintained; evaluates the input it receives from receptors and generates output commands when
they are needed
efferent pathway - (ANSWER)flow away from control center to effector
effector - (ANSWER)body structure receiving output and brings about change and produces a response
that alters the controlled condition
negative feedback system - (ANSWER)reverses a change in a controlled condition
positive feedback loop - (ANSWER)strengthens or reinforces a change in the controlled condition until its
interrupted-effector produces a response that reinforces the initial change-child birth
disorder - (ANSWER)abnormality of a structure or function
disease - (ANSWER)illness characterized by a recognizable set of signs and symptoms
symptom - (ANSWER)subjective changes not visible to the observer
sign - (ANSWER)objective changes visible to the observer (doctor)
