Q

what are the main components of an ANS pathway?

A

pre-ganglionic neuron
post-ganglionic neuron
effector organ

17
Q

what are the components of a normal SNS pathway pre-ganglionic neuron?

A

short, myelinated, releases acetylcholine, binds to nicotinic cholinergic receptor

18
Q

what are the components of a normal SNS pathway post-ganglionic neuron?

A

long, unmyelinated, releases norepinephrine, binds to andrenergic receptor

19
Q

what are the components of a sweating SNS pathway’s pre-ganglionic neuron?

A

short, myelinated, releases acetylcholine, binds to a nicotinic cholinergic receptor

20
Q

what are the components of a sweating SNS post-ganglionic neuron?

A

long, unmyelinated, releases acetylcholine, binds to a muscarinic cholinergic receptor

21
Q

what are the components of a adrenal gland SNS pre-ganglionic neuron?

A

short, myelinated, releases acetylcholien, binds to a nicotinic cholinergic receptor

22
Q

what does the adrenal gland release in the SNS pathway?

A

epinephrine into the bloodstream

23
Q

true or false: there is a post-ganglionic neuron present in an adrenal gland SNS pathway

A

false
