Q

Which NT is dopamine similar to and what is its mechanism of action?

Q

What are ganglia and what is their purpose?

A

clusters of neuron cell bodies OUTSIDE the CNS that serve as synapse stations for ANS

17
Q

WHat do both major control systems use to transmit info as messengers?

A

Both use Chemicals

Endocrine: uses hormones Nervous: uses NT

18
Q

Define: Sensory division

A

or Afferent division: nerve fibers that carry info to the CNS

19
Q

What are the two types of cholinergic receptors?

A

remember that it binds with ACH Muscarinic and Nicotinic receptors

21
Q

the ANS has what type of control over which muscle or tissue?

A

Involuntary control (vs voluntary like the somatic ) over smooth muscle, cardiac muscle and glandular tissue

23
Q

What are the two major nervous systems?

A

CNS and PNS

24
Q

Where are the beta1 and beta2 adrenergic receptors found?

A

1 heart, 2 lungs

beta1- primarily in the heart

beta2- in smooth muscle like bronchioles, arterioles, and visceral organs

26
Q

Define: synapse

A

junction btw nerves

27
Q

What is in the gray matter of the CNS?

A

neuron cell bodies, tracts and unmyelinated axons

28
Q

Name the excitatory NT’s and what they do?

A

They stimulate(*excite*) the nerve impulse: dEANs

EPI, ACH, NE

28
Q

Adrenergic receptors are sub-divided into which receptors and what do they bind to?

A

Alpha-adrenergic receptors- binds to NE

Beta-adrenergic receptors- binds to EPI

28
Q

What are the effects of the beta2 adrenergic agonist drugs?

A

2 lungs- bronchodilation, uterine relaxation, glycogenolysis in the liver (glycogen–>glucose)

29
Q

Neurons have two specialized extensions: axons and dendrites. Which conducts toward the cell and which conducts away from the cell?

A

dendrites: conduct toward the cell

Axons: conduct Away from the cell

30
Q

What are the effects of alpha adrenergic agonists?

A

vasoconstriction and stimulation the CNS, male ejaculation, decreased insulin release

32
Q

Name the 3 Types of NT receptors?

A

*CAD*

Cholinergic- binds to ACH

Adrenergic- binds to Catecholamines (EPI, NE)

Dopaminergic- binds to dopamine

33
Q

which bodily functions are regulated by the ANS?

A

RUBDoWn- BH

Respiration

Urinary excretion

BP Digestive fx

Water balance

Body Temp

Heart Rate

35
Q

Sympathetic branch is known as what?

A

fight or flight

36
Q

What are the functions of the ANS?

A

regulate and integrate the body’s internal functions

integrate parts of the CNS and PNS to react to changes in the internal and external environment

37
Q

parasympathetic is known as what?

A

rest and digest

38
Q

Nervous–>PNS–> MOTOR division–> ANS is divided into??

A

Sympathetic and Parasympathetic branch

39
Q

Where are preganglionic neuron cell bodies located?

A

inside the CNS *** (CNS)pregang—ganglia synapse ANS—post(PNS)

40
Q

Where are the beta1 adrenergic agonists located?

A

1 heart- located in the myocardium AV node and SA node

41
Q

What are the effects of the beta1 adrenergic agonist drugs?

A

cardiac stimulation: positive inotropic(force of contraction), positive chronotropic (heart rate), and positive dromotropic effect (conduction speed of AV node).

42
Q

What is the PNS divided into?

A

Sensory and Motor divisions

43
Q

why are NT, axons, and neurons imp in pharm?

A

Bc many drugs act like NT, some block the NT form binding to its receptor and some enhance NT action

44
Q

Define: Motor Division

A

or Efferent division (E for effort of a motor): nerve fibers that carry impulses away from the CNS, to the effector cell/tissue

45
Q

What are other names of adrenergic-blocking agents?

A

adrenergic antagonist or sympatholytics

47
Q

Name the Inhibitory NT’s and what they do?

A

They inhibit the nerve impulse. (DeanS + G)

Dopamine, Serotonin and GABA

48
Q

what are cholinergic agonists?

A

drugs that bind to cholinergic receptors- act like ACH aka parasympathomimetics

49
Q

When NT crosses the synapse what does it bind with on the effector structure (target tissue)?

A

Specific Receptors
