Question	Answer	Question	Answer
2 subdivisions?	Parasympathetic (PNS)Sympathetic (SNS)	Neurotransmitters?	Receptor type determines which neurotransmitter will act on target cells
Prime goal of the ANS?	maintain homeostasis	2 classes of ANS receptors?	Cholinergic-respond to Ach.Adrenergic-respond to Norepi
what happened at rest, and after feeding?	PNS dominates control	where is Adrenergic Receptors 2 subclasses located?	Alpha, Beta
what happend during activity and stress?	SNS dominates control	Properties of Alpha Adrenergic Receptors	Located in effector organs of sympathetic nervous systemMost commonUsually excitatoryAffinity greater for norepinephrine than epinephrine
Parasympathetic Activity	Quiet, relaxed statesActive in “rest and digest”Increase gastrointestinal activitiesDecrease heart rate and blood pressure	Beta Receptors	Act on Gprotein systems to increase cAMP activityCan be activated by both norepi and epi
Sympathetic Activity	Fight-or-flight response
how many neurotransmitters secreted at target cells?	2 of them (PNS-Acetylcholine (Ach)SNS-Norepinephrine (Norepi)Cells that secrete Ach-cholenergicCells that secrete Norepi-adrenergic)
