17
Q

autonomic NS preganglionic NT released

A

ACh

18
Q

autonomic NS pregagnlionic effect of NT on target

A

excitatory - stimulates action potential in postganglioninc neuron

19
Q

autonomic NS postganglionic location

A

peripheral ganglion

20
Q

autonomic NS postganglionic NT released

A

ACh or NA

21
Q

autonomic NS postganglionic effect of NT on target

A

excitatory - target activity increase, inhibitory - target activity decreases

22
Q

parasympathetic size of axons

A

preganglionic axon - long, postganglioninc axon - short

23
Q

sympathetic size of axons

A

preganglionic axon - short, postganglioninc axon - long

24
Q

adrenal medulla

A

enhance and prolong the sympathetic response

25
Q

preganglionic neurons release

A

ACh

26
Q

postanglioninc neurons release

A

sympathetic - NA, parasympathetic - ACh

27
Q

receptors that bind acetylcholie (ACh) are called

A

cholinergic

28
Q

receptors that bind noradrenaline (NA) are called

A

adrenergic

29
Q

2 subtypes of cholinergic receptors

A

nicotinic and muscarinic

30
Q

2 subtypes of adrenergic receptors

A

alpha, beta

31
Q

beta 1 location

A

heart

32
Q

beta 1 effect of NT binding

A

excitatory - increases heart rate and contractions

33
Q

beta 1 location

A

airways, blood vessels (heart, liver, skeletal muscle), digestive tract, urinary organs

34
Q

beta 1 effect of NT binding

A

inhibitory - decreased activity

35
Q

alpha 1 location

A

blood vessels (except heart, liver, skeletal muscles), all sympathetic targets

36
Q

alpha 1 effect of NT binding

A

excitatory - increased activity

37
Q

agonists

A

drugs that mimic the action of the NT - promote normal response

38
Q

antagonists

A

drugs that bind the receptors and block the action of NT - prevent normal response

39
Q

biogenic amines

A

noradrenaline, dopamine, serotonin

40
Q

amino acids

A

GABA, glutamate

41
Q

neutopeptides

A

substance P, endorphins
