Question 8

Question 9

Ejaculation is part of which division?

Answer 9

Sympathetic

Question 10

Parts of male sexual function

Answer 10

1. Erection

2. Ejaculation

Question 11

What is the sympatho-mimetic function?

Answer 11

Imitate the sympathetic nervous system

Question 12

What is the sympatho-lytic function?

Answer 12

Destroy the sympathetic nervous system

Question 13

What is the parasympatho-mimetic function?

Answer 13

Imitate the parasympathetic nervous system

Question 14

What is the parasympatho-lytic function?

Answer 14

Destroy the parasympathetic nervous system

Question 15

Drug class question:
If heart rate is very low what drug(s) should be given?

Answer 15

1. Sympatho-mimetic, since it is adrenalin to try to speed heart rate up.
2. If no success use Parasympatho-lytic, since it will shut down the parasympathetic division which is causing the slow heart rate.

Question 16

Drug class question:
During an asthma attack what drug(s) should be given?

Answer 16

1. Sympatho-mimetic, since it will dilate the currently constricted blood vessels. (remember para has no business with blood vessels)

Question 17

Drug class question:
During an overdose what drug should be given?

Answer 17

1. Parasympatho-lytic, since it will stop the digestion of the poison.
