Autonomic bitch

Question 1

which are myelinated: pre or post ganglionic nerves

Answer 1

pre

Question 2

what are the three ways synaptic preganglion fibers can go

Answer 2

1) innervate ganglionic nerve in the same ganglion
2) go up or down sympathetic chain to synapse with a ganglion in a different chain ganglion
3) bypass sympathetic chain and innervate collateral ganglion

Question 3

what do we call a sympathetic ganglion outside of the sympathetic chain

Answer 3

collateral ganglion

Question 4

what is special about the adrenal glands innervation

Answer 4

the adrenal gland is innervated by the preganglionic fiber itself

Answer 5

long

Question 6

parasympathetic has long or short post synaptic fubers

Answer 6

short

sympathetic have short or long presynaptic fibers

Answer 7

short

Question 8

sympathetic have short or long postsynaptic fibers

Answer 8

long

Question 9

what neurotransmitter does the sympathetic NS release from the postsynaptic fibers

Answer 9

norepinepherine

Answer 16

excitatory

Question 17

what dictates whether its excitatory or inhibatory in the autonomic NS

Answer 17

the type of receptors

Question 18

ACh effect, excitatory or inhibitory in autonomic NS

Answer 18

either, depends on the receptors

Question 22

what is the effect of ACh binding to nicotonic receptors

Answer 22

stimulatory

Question 23

what 3 locations are nicotinic receptors found

Answer 23

motor end plates
all ganglionic neurons of both autonomic division
hormone producing cells of adrenal medulla

Question 24

what is the effect of ACh binding to muscarinic receptors

Answer 24

either

Question 25

where do muscarinic receptors occur

Answer 25

all effector cells innervated by postganglionic cholinergic fibers

Question 26

what three locations does ONLY the sympathetic division innervate

Answer 26

what is the master controller of the ANS

Answer 29

hypothalamus
