norepinephrine (noradrenaline) inhibition,
platelet activation.

Question 3

a2 receptor stimulants

Answer 3

Epinephrine = norepinephrine > isoprenaline.

Question 4

B1 adrenergic recpetors

Answer 4

Positive Chronotropic, Dromotropic and inotropic effects, increased amylase secretion.

Question 5

B1 receptor stimulants.

Answer 5

Isoprenaline > epinephrine = norepinephrine.

Question 6

Positive chronotrophic effect.

Answer 6

Increases heart rate.

Question 7

Positive dromotrophic effect.

Answer 7

Increases the conduction speed at the AV node, and therefore the rate of electrical impulses that stimulate heart rate.

Question 8

Positive inotrophic effects.

Answer 8

Increases the strength of the heart’s muscular contractions.

Question 9

B2 adrenergic receptors.

Answer 9

Smooth muscle relaxation (Ex. Bronchodilation).

Question 10

B2 receptor stimulants.

Answer 10

Isoprenaline > epinephrine&raquo_space; norepinephrine

Question 11

B3 adrenergic receptor

Answer 11

Enhance lipolysis, promotes relaxation of detrusor muscle in the bladder.

Question 12

B3 receptor stimulation.

Answer 12

Isoprenaline = norepinephrine > epinephrine.

Question 13

a1 adrenergic receptor.

Answer 13

Smooth muscle contraction,
mydriasis,
vasoconstriction in the skin, mucosa and abdominal viscera
& sphincter contraction of the GI tract and urinary bladder.
