Question 1

what is the NS divided into again?

Answer 1

central and peripheral

Question 2

the autonomic nervous system is divided into what two parts anatomically?

Answer 2

sympathetic (thoracolumbar)
-fight or flight
parasympathetic (craniosacral)
-rest and digest/feed and breed

Question 3

what are the fight or flight autonomic responses?

Answer 3

pupils dilate
heart rate increases
resp rate increases/bronchi dilate
muscles tense
digestion slows
salivation ceases
inhibits bladder contraction

Question 4

what are the rest and digest autonomic responses?

Answer 4

pupils constrict
heart rate decreases
resp rate decreases/bronchi constricts
digestion stimulated
salivation increases
bladder contraction
sexual arousal

Question 5

almost all efferent fibers leaving the CNS are _____?

Answer 5

cholinergic b/c preganglionic neurons release acetylcholine

Question 6

what receptors are found in the cholinergic system?

Answer 6

nicotinic acetylcholine receptors

muscurinic acetylcholine receptors

Question 7

in the autonomic nervous system what do drugs do?

name an example

Answer 7

mimic or block the actions of chemical transmitters

nicotine is a direct agonist at nicotinic receptors which causes skeletal muscle contraction like weakness and fasciculations
