HomeostasisStable internal environment Involves
1. Receptor – senses stimulus2. Control Center – receives and processes info3. Effector – responds to stimulus4. Pathways
1. Afferent (receptor to control center)2. Efferent (control center to effector)
Homeostasis as Room Temp1. Thermometer (receptor) notices higher
room temp (stimulus)2. Thermostat (control center) receives and
processes info3. Air conditioner (effector) turns on
Homeostatic FeedbackNegative Feedback: a variation outside
normal limits triggers an automatic response that corrects the situationie: body temperature, hormone regulation,
blood pressure Positive Feedback: the initial stimulus
produces a response that reinforces that stimulus ie: clotting, birth contractions, lactation
