21
Q

Pancreas second adrenergic receptor type and response

A

B2, increased insulin

22
Q

Releasers

A

Help drive the release of neurotransmitters

23
Q

Reuptake Inhibitors

A

There is an inhibition leading to a longer acting adrenaline or epinephrine at synapse

24
Q

Hypertensives

A

Nasal decongestants and appetite suppressants

25
Q

Sympathomimetic Drugs

A

Used for raising blood pressure by stimulating the heart and inducing vasoconstriction

26
Q

Sympatholytic Drugs

A

Block sympathetic adrenergic system through, alpha and beta receptor antagonists, ganglionic blockers, and drugs that black sympathetic activity in the brain before signal can leave the brain

27
Q

Antihypertensives

A

Decrease heart rate and blood pressure

28
Q

Muscarinic receptor response

A

Excitatory or inhibitory

29
Q

Nicotinic receptor response

A

Short and excitatory

30
Q

Cholinergic neurons

A

Neurons that synthesize and release ACh

31
Q

Function of parastmpatholytic drugs

A

By blocking the parasympathetic nervous system they increase heart rate, open up airways, and reduce mucous production in asthma patients
