receptors
This increases chronotrropicity and inotropicity
Beta 1 receptors
Where do nerves originate in the parasympathetic NS
medulla and sacral area
600 pts
What is the primary neurotransmitter in the PNS systems
acetylcholine
This causes vasoconstriction
alpha 1 receptors
No :( most have ganglia within target organ (no midway ganglia)
700
What innervates the SA and AV node
post-ganglionic fibers
This causes bronchodilation and vasodilation
beta 2 receptors
What is made of prostaglandin fibers
Vagus nerve
100 points for everyone that is right
PNS effects
-pupil constriction
-decrease chonotropicity
-increase digestive activity
-increase digestive secretions
-sexual simulation.
What is the primary neurotransmitters (postganglionic)
Norepinephrine and dopamine
Receptors in the heart are called what for PSN
M2 muscarinic receptors
M3 muscarinic receptors
