What is the function of the PSNS
rest and digest, promotes the survival of individual or species
What is the NT of the PSNS
Ach
What is a nicotinic receptor
sysnapse between preganglionic and postganglionic, both SNS and PSNS
Is nicotinic receptor excitatory or inhibitory
excitatory
What is a muscarinic receptor
the response to Ach, PSNS
Are muscarinic receptors excitatory or inhibitory
both
Does the PSNS fibers travel to skin and arteries
No
What is the function of the SNS
fight or flight, dealing with stress
What is the neurotransmitter of the SNS
mostly NE
What does the SNS do to the pupils
dilate
What does the SNS to salivary secretions
decrease
What does the SNS do to reticular activating system
increase
What does the SNS do to bronchi
dilate (increase air)
What does the SNS do to heart rate
increase
What does the SNS do to the breakdown of fats(glucose)
increase
digestive, urinary, and reproduction in the SNS
decrease, increase sphincter close
What is a paradoxical reaction in SNS
when soil/wet self, unusual
Blood flow to digestive, urinary, reproductive systems, and skin in SNS
decrease
Blood flow to heart, brain, and skeletal muscles in SNS
increase
What is dually innervated
Viscera, smooth muscle, glands, heart, pupils
What has the most control over the autonomic nervous system
hypothalamus
what part of the hypothalmus control the SNS
posterior
What part of the hypothalamus controls the PSNS
anterior
What do Mimetic drugs do
Mimic either PSNS or SNS
What do mimetic drugs do in the SNS (release, breakdown, receptors)
Increase release of NE, inhibit breakdown of NE, binding to and stimulating NE receptors
What do mimetic drugs do in the PSNS (release, breakdown, receptors)
increase release of Ach, inhibit breakdown of Ach, binding to and stimulating Ach receptors
What are blockers
inhibit/ block systems
What do blockers do in the SNS (release, breakdown, receptors)
decrease release of NE, Increasing breakdown of NE, blocking NE receptors
What do blockers do in the PSNS (release, breakdown, receptors)
Decrease release of Ach, increase breakdwon of Ach, blocking Ach receptor
