17
Q

What is another name for the parasympathetic nervous system?

A

craniosacral nervous system

18
Q

Where do the SNS preganglionic neurons leave the CNS?

A

thoracolumbar spinal cord

19
Q

What is another name for the SNS?

A

thoracolumbar nervous system

20
Q

Where are the preganglionic cell bodies of the SNS located?

A

lateral horn of T1-L3

21
Q

Where are the SNS ganglia located?

A

sympathetic trunk, close to the spinal cord

22
Q

Which hormones are stimulated by the sympathetic nervous system?

A

Epi and NorEpi

23
Q

Where are the parasympathetic ganglia located?

A

within the effector organ

24
Q

Where are the preganglionic PNS neurons exiting the CNS

A

CN III, VII, IX, and X. S1-S3

25
Q

Preganglionic NTs

A

both SNS and PSN use Ach and nicotinic receptors

26
Q

Postganglionic NTs

A

SNS uses NE/E on alpha and beta receptors
PNC uses Ach which acts on muscarinic receptors on effector organs

A

SNS only!
