1

What is the sympathetic division also known as?

Tharacolumbar

2

What is the parasympathetic division also known as?

Craniosacral

3

What is the function of the sympathetic system?

Fight or flight response

4

Which system has longer preganglionic fibers?

Parasympathetic

5

Which system system has longer postganglionic fibers?

Sympathetic

6

What are the pre ganglionic NTs for the sympathetic division?

ACh

7

What are the pre ganglionic NTs for the parasympathetic division?

ACh

8

What is the postganglionc receptor antagonist for both divisions?

Nicotinic (fast/ionotropic)

Nicotine

9

What are the post ganglionic NTs for the sympathetic division?

NE and E (sweat glands use ACh)

10

What are the post ganglionic NTs for the parasympathetic division?

ACh

11

What type of receptors do sympathetic fibers use at the target organ?

Adrenergic (slow/metabotropic)

Phenylephrine and isoproterenol are the agonists.

12

What type of receptors do parasympathetic fibers use at the target organ?

Muscarinic (slow/metabotropic)

Muscarine is the agonist

13

Ionotropic/Fast

nicotinic AChR

14

What is the post-synaptic receptor type for neuron-viscera junctions?

Metabotropic/Slow

muscarinic AChR

15

What is the post-synaptic receptor type for neuron-skeletal muscle junctions?

Ionotropic/Fast

nicotinic AChR

16

What is the neuron-neuron postsynaptic potential?

EPSP/IPSP

17

What is the neuron-viscera postsynaptic potential?

Junction Potential

EJP/IJP

18

What is the neuron skeletal muscle postsynaptic potential?

EPP
