Ch 18 Adrenergic Drugs

Front 1

Adrenergic agonists

Back 1

Drugs that stimulate and mimic the actions of the sympathetic nervous system

Front 2

Adrenergic receptors

Back 2

Receptor sites for the sympathetic neurotransmitters norepinephrine and epinephrine

Front 3

Alpha-adrenergic receptors

Back 3

A class of adrenergic receptors that are further subdivided in alpha1 and alpha2 adrenergic receptors, and are differentiated by their anatomic location in the tissues, muscles, and organs regulated by specific autonomic nerve fibers

Front 4

Autonomic functions

Back 4

Bodily functions that are involuntary and result from the physiologic activity of the autonomic nervous system. The functions often occur in pairs of opposing actions between the sympathetic and parasympathetic divisions of the autonomic nervous system.

Front 5

Autonomic nervous system

Back 5

A branch of the peripheral nervous system that controls autonomic bodily functions. It consists of the sympathetic nervous system and the parasympathetic nervous system.

Front 6

Beta-adrenergic receptors

Back 6

Receptors located on postsynaptic effector cells of tissues, muscles, and organs stimulated by specific autonomic nerve fibers.

Front 7

Catecholamines

Back 7

Substances that can produce a sympathomimetic respone

Front 8

Dopaminergic receptor

Back 8

activated by binding of the neurotransmitter dopamine

Front 9

Mydriasis

Back 9

Pupillary dilation

Front 10

Ophthalmics

Back 10

Drugs that are used in the eyes

Front 11

Positive chronotropic effect

Back 11

An increase in Heart rate

Front 12

Positive dromotropic effect

Back 12

Increase in the conduction of cardiac electrical impulses through the atrioventricular node, which results in the transfer of nerve action potentials from the atria to the ventricles

Front 13

Positive inotropic effect

Back 13

An increase in the force of contraction of the heart muscle

Front 14

Sympathomimetics

Back 14

Drugs that mimic the catecholamines epinephrine, norepinephrine, and dopamine

Front 15

Synaptic cleft

Back 15

the space either between two adjacent nerve cell membranes or betweena nerve cell membrane and an effector organ cell membrane

Front 16

Alpha1 receptor Cardiovascular

Back 16

Vasoconstriction

Front 17

Beta2 receptor Cardiovascular

Back 17

Vasodilation

Front 18

Beta1 Cardiovascular

Back 18

Increased contractility; Increased Heart rate

Front 19

Alpha1 endocrine

Back 19

Glycogenolysis

Front 20

Beta2 endocrine

Back 20

Gycogenolysis

Front 21

Beta1 Endocrine

Back 21

Increased renin secretion

Front 22

Alpha1 Gastrointestinal

Back 22

Decrease motility(relaxation of gastrointestinal smooth muscle)

Front 23

Beta2 Gastrointestinal

Back 23

Decrease motility(relaxation of gastrointestinal smooth muscle)

Front 24

Alpha1 Genitourinary

Back 24

Constriction of the bladder sphincter; Causes male ejaculation; female uterine contaction

Front 25

Beta2 Genitourinary

Back 25

Causes relaxation of genitourinary tract

Front 26

Beta2 Respiratory

Back 26

Causes bronchial Dilation (relaxation of bronchial smooth muscles)

Front 27

Alpha1 Ocular

Back 27

Causes Mydriasis (Pupillary dilation)

Front 28

Dopaminergic receptor

Back 28

When stimulated by DOPAMINE, cause vessels of the renal, mesenteric, coronary, and cerebral arteries to dilate, which increases blood flow to these areas

Front 29

Adrenergic drugs

Back 29

Drugs that mimic the effects of the SNS neurotransmitters, epinephrine, norepinephrine, and dopamine.
