1
Q

Preganglionic sympathetic neurons release

A

Actylcoline

2
Q

Post ganglion sympathetic neurons release

A

Norepinephrine

3
Q

Reserpine

A

Long lasting
Inhibits vesicular monamine transporter
Horses

4
Q

What makes the adreanal gland different

A

No postganglionic neurons

Release both epi and norepi

5
Q

What makes the sweat gland different in the ANS

A

Sweat gland releases acetylcholine for both Preganglionic and postganglionic

6
Q

A1 receptor

A

Gp
Smooth muscle
Causes contraction
Epinephrine>norepi>isoproterenol

7
Q

What causes one drug to have multiple effects

A

Different receptors

8
Q

B1 receptors

A

Heart
Contraction
Isoproterenol>epi>norepi

9
Q

Pre synaptic receptors

A

important in CNS

Control transmitter release

10
Q

Parasympathetic neurons release

A

Acetylcholine for both pre and postganglion

11
Q

What happens if you inhibit Ach synthesis

A

DEATH

12
Q

How is Ach eliminated

A

Enzymatic

13
Q

What is the major post synaptic receptor target for drugs

A

M3

14
Q

Pharmacological antagonism

A

Blockade of an agonist by an antagonist

15
Q

Physiological antagonism

A

Opposing actions produced by two drugs via actions on different receptors or via distinct mechanisms

16
Q

Benefits of physiological antagonism

A

Provides diverse set of pharm agents to treat conditions

Allows for complimentary treatments that target both branches of the autonomic nervous system
