quiz 6 agonists antagonists ad autnomic

Question 1

variety of what embedded in membrane of cells around the body

Answer 1

receptors

Question 2

what are receptors looking for

Answer 2

a specific signal or signals which will cause them to do certain things

Question 3

agonist

Answer 3

any chemical that binds to a receptor and activates it

Question 4

antagonists

Answer 4

some chemicals that bind to the same receptors but do not turn them on, instead they sit on the receptor and block them from being activated

Question 5

agonist alone

Answer 5

full activation

Question 6

agonist and antagonist

Answer 6

less activation

Question 7

antagonist alone

Answer 7

no activation

Question 8

Answer 8

control the body’s involuntary muscles

Question 9

2 parts of the autonomic nervous system

Answer 9

parasympathetic (PSNS)

Sympathetic (SNS) nervous systems

in battle, one trying to overtake or outweighs the other

Question 11

sympathetic nervous system response

Answer 11

fight or flight

Question 12

two hormones released in sympathetic nervous system

Answer 12

epinephrine (adrenaline) and norepinephrine

sympathetic NS is going to do what things necessary to survive interaction with sabertooth tiger

Answer 13

• heart rate/ volume up
• airway dilates
• blood pressure up
• glycogenolysis in liver
• pupils dilate
• respiratory rate up
• blood shunted away from GI

Question 14

glycogenolysis

Answer 14

breaks won glycogen into glucose

Question 15

adrenergic receptor

Answer 15

any receptor where epinephrine or norepinephrine can bind

Question 16

adrenergic receptors come in

Answer 16

variety of shapes and sizes and do different things, but are all part of the sympathetic nervous system

Question 17

subtypes of adrenergic receptors

Answer 17

alpha-1, alpha-2, beta-1, beta-2, beta-3

Question 18

parasympathetic nervous

rest or digest (feed or breed)

Question 19

main hormone involved in parasympathetic nervous system

Answer 19

Acetylcholine (ACh)

Question 20

parasympathetic nervous system will not help you

Answer 20

fight saber tooth tiger

Question 21

what does the parasympathetic nervous system do

Answer 21

SLUDGE-PM

Question 22

what does SLUDGE-PM

Salivation (drooling)
Lacrimation (tearing up)
Urination (peeing)
Diaphoresis (sweating)
GI upset (diarrhea)
Emesis (vomiting)
Priapism (erection)
Miosis (pupils constrict)

Question 23

speed of parasympathetic response

Answer 23

much slower than sympathetic

Question 24

receptors activate when acetylcholine binds to them

Answer 24

cholinergic receptors

Question 25

two types of cholinergic receptors

Answer 25

muscarinic receptors and nicotinic receptors

Question 26

subtypes of muscarinic and nicotinic receptors

Answer 26

M1 through M5 muscarinic receptors and N1 and N2 nicotinic receptors

Question 27

activation of cholinergic receptors causes

Answer 27

some of the SLUDGE-PM response to happen

Question 28

what happens when acetylcholine binds to M2 receptors in heart

Answer 28

slow heart rate

Question 29

what does atropine do

Answer 29

blocks M2 receptors, stopping ACh from binding there

Question 30

what type of chemical is atropine

Answer 30

antagonist

Question 31

who would give atropine to

Answer 31

people whose hearts you want to go faster

Question 32

beta-1 receptors

Answer 32

located mostly on the heart, norepinephrine and epinephrine can bind to it

Question 33

who do you give beta blockers to

Answer 33

people whose hearts you don't want to beat too fast , (people with heart diseaseproblem) could stop heart attack

Question 34

what happens when norepinephrine and epinephrine bind to beta -1 receptors

Answer 34

the heart beats harder and faster

Question 35

what is the suffix for a beta blocker

Answer 35

olol

Question 36

what are beta blockers

Answer 36

drugs that block beta-1 receptors from binding norepinephrine and epinephrine

Question 37

epinephrine also binds to which receptors located around the body

Answer 37

beta-2 receptors

Question 38

what happens when epinephrine binds to beta-2 receptors

Answer 38

the muscles in the bronchi (in lungs) relax, which allows the bronchi to expand

Question 39

EpiPEns do wha

Answer 39

inject epinephrine straight into the bloodstream

Question 40

what would epipens do to BP/ HR

Answer 40

Heart rate gets faster and blood pressure raises

Question 41

what would epipens do in anaphylaxis

Answer 41

it allows airways to relax and get bigger

PSNS and SNS run through what

Answer 42

CNS (spinal cord)

Question 43

severe neck/spine injury can wipe out what

Answer 43

sympathetic and parasympathetic nervous systems

Question 44

PSNS is much slower in what than SNS

Answer 44

being wiped out by severe neck/spine injury

Question 45

PSNS system takes longer to disappear because

Answer 45

hormones linger around

Question 46

what is the result of PSNS taking longer than SNS to dissappear

Answer 46

PSNS is full force for a few units

Question 47

Answer 47

priapism

Question 48

people hanged to death often experience
