This photo shows a child receiving an oral vaccine againstpolio, a disease caused by a virus that infects neurons. Giventhat the body cannot readily replace most neurons, why isit important that a polio vaccine stimulate not only acell-mediated response but also a humoral response?
;Make a Venn Diagram using the provided information below NEGATIVE FEEDBACK MECHANISM • Most control mechanisms in the human body are negativefeedback mechanisms• A negative feedback mechanism DECREASES theintensity of the stimulus and eliminates it• When a variable is above or below set point, integratortriggers a move in the OPPOSITE DIRECTION to reachthe set valueEx. Body temperature, blood pressure, pH and CO2 levels,blood glucose levelsPOSITIVE FEEDBACK MECHANISM• A positive feedback mechanism ENHANCES the originalstimulus to ACCELERATE activity• Integrator triggers a move in the SAME DIRECTIONtriggering an “explosive” response• Positive feedback mechanisms are less commonEx. Blood clotting, childbirth (oxytocin)
