Question

Which of the following correctly describes the order of events occurring during a sympathetic nervous system response?

Stimulation of cranial or sacral spinal regions; impulse reaches cranial root ganglion; acetylcholine release
Stimulation of cranial or sacral spinal regions; impulse reaches cranial root ganglion; norepinephrine release
Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; acetylcholine release
Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; norepinephrine release

Answer 1

@whpalmer4 would you know anything about this one?

Answer 2

Not off the top of my head, but let's see if we can work it out.

Answer 3

Alright. Well I KNOW the sympathetic chains use chain ganglia. It's only parasympathetic that use cranial ganglia.

Answer 4

So that eliminates A and B and leaves the possible answers as C and D.

Answer 5

acetylcholine causes epinephrine and norepinephrine release, no?

Answer 6

hm, let me look that one up because I don't remember that exactly

Answer 7

I know epinephrine and non-epinephrine are produced by the adrenal glands...

Answer 8

too bad my uncle the neuroanatomy professor has moved on to the great beyond, eh? :-)

Answer 9

I could ask my mom and sister because they're both doctors but they're also both sleeping so
