drugs categories

Question 1

cholinergic drugs

Answer 1

mimic the PNS - rest and digest

Question 2

anti-cholinergic drugs

Answer 2

block PNS symptoms - symptoms are similar to SNS

Question 3

adrenergic drugs

Answer 3

mimic the SNS

Question 4

adrenergic antagonists

Answer 4

block SNS symptoms - symptoms are similar to PNS

Question 5

• Nicotinic N- Neural

Answer 5

o Location: all autonomic nervous system ganglia and the adrenal medulla
o Response to activation: stimulation of parasympathetic and sympathetic postganglionic nerves and release of epinephrine from the adrenal medulla

Question 6

• Nicotinic M – Muscular

Answer 6

o Location: Neuromuscular junction

o Response: Contraction of skeletal muscles

Question 7

• Muscarinic – located on target organs of PNS – activation causes

Answer 7

o Location: All parasympathetic target organs
o Responses:
 Eyes: contraction of the ciliary muscle focuses lens for near vision
 Eyes: Contraction of the iris sphincter muscle causes miosis (constriction)
 Heart: Decreased rate
 Lung: constriction of bronchi, promotion of secretions
 Bladder: urine to leave bladder
 GI Tract: salivation, increased gastric secretions, increased intestinal tome and motility, defecation
 Sweat glands: generalized sweating
 Sex organs: erection
 Blood vessels: vasodilation

Question 8

• Alpha1

Answer 8

o Location: Eye
 Response: Contraction of the radial muscle of the iris causes mydriasis – pupil dilation
o Location: Arterioles – skin, viscera, mucous membranes
 Response: constriction
o Location: Veins
 Response: Constriction
o Location: Sex Organs – Male
 Response – Ejaculation
o Location: Bladder
 Response: Contraction of trigone and sphincter – cant pee

Question 9

• Alpha 2

Answer 9

o Location: Presynaptic nerve terminals

 Response: inhibition of transmitter release

Question 10

• Beta 1

Answer 10

o Location: Heart
 Response: increases rate, increased force of contraction, increased AV conduction velocity
o Location: Kidneys
 Response: Release of renin

Question 11

• Beta 2

Answer 11

o	Location: Arterioles of the heart, lung, skeletal muscles
	Response: dilation
o	Location: Bronchi
	Response: dilation
o	Uterus
	Response relaxation
o	Liver
	Gycogenolysis 
o	Skeletal Muscles 
	Enhanced contraction, glycogenolysis

Question 12

• Dopamine

Answer 12

o Location: Kidney

 Dilation of kidney vasculature
