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)
