1

What is an adrenergic?

Refers to a drug stimulating a receptor for nor-epinephrine or epinephrine

2

What is an afferent signal?

Signal from peripheral to Brain and spinal cord.
Bottom-up signal

3

What is anti-adrenergic?

Drug blocking receptors for nor-epi and epi

4

What is anti-cholinergic?

Refers to drug blocking receptor for ACH

5

What is cholenergic?

Drugs that stimulate of a receptor for ACH

6

What is efferent?

Signals that come from brain/spinal cord to peripherals
top-down

7

What is norepinephrine?

Naturally occurring catecholamine neurotransmitter in the sympathetic terminal sites

8

What is parasympatholytic?

agents that inhibit or block effects in the parasympathetic nervous system

9

What is Parasympathomimetic?

Agents that cause stimulation of the parssympathetic nervous system

10

What is sympatholytic?

Agents that block or inhibit the effects of the sympathetic system

11

What is sympathomimetic?

Drugs that mimic the effects of the sympathetic system.

12

The sympathetic and parasympathetic system belong to what system?

The autonomic nervous system

13

What does parasympathetic system control?

-it control day to day bodily function.
CAUSES SLUD.

14

What is SLUD?

-salivation
-lacrimation
-urination
-defecation

15

What does stimulation of the sympathetic system do?

It is characterized as the flight or fight response.

16

What is the neuroeffector site?

The terminal nerve site for parasympathetic or sympathetic system.
-where ACH ends for muscarinic parasympathetic system
-epi and nor epi for sympathetic systems

17

What is another word for cholinergic?

Parasympathomimetic

18

What is another word for anti-cholinergic?

Parasympatholytic

19

What is another word for adrenergic?

Sympathomimetic

20

What is another word for anti-adrenergic?

Sympatholytic

21

Effects of Parasympathetic stimulation on heart
(SA node and contractility)

- SA NODE slowing of rate(decreased HR)
-decreased contractility (decreased atrial force)

22

Effects of Parasympathetic stimulation on lungs
(On muscle and on mucous glands)

-construction of smooth muscle
-increased mucous secretion

23

What is ACH?

Acetylcholine

The chemical used in nerve impulses at all pre ganglionic sites but only in post ganglionic sites of the parasympathetic system

24

Effects of Parasympathetic stimulation on blood vessels

Vasoconstriction,

-increased blood pressure due to loss of elasticity

25

Effects of sympathetic stimulation on heart

Increased heart rate, increased contractility

26

Effects of sympathetic stimulation on lungs

Bronchodilation
Beta 2 effect

27

Effects of sympathetic stimulation on blood vessels

Vasodilation

28

What is an M1 innervation do?

Increased secretion in nasal passages

29

What is an M3 innervation do?

Bronchoconstriction of the airways

30

What is an M2 innervation do?

Decreased heart rate and decreased contractility
