8. under adrenergic stimulation, these type α1 receptors
of receptors constrict blood vessels, thus
restrict blood flow and increase blood
pressure:
9. under adrenergic stimulation, these type β2 receptors
of receptors dilate blood vessels, thus in-
crease blood flow in those vascular beds:
10. under adrenergic stimulation, these type α1 receptors
of receptors dilate the pupils (mydriasis)
by contracting the radial muscles of the
iris:
11. __________ (such as phenylephrine) are a1 agonists
used as nasal decongestants because they
constrict precapillary arterioles so capillar-
ies stop leaking into the swollen weaping
extravascaular tissues of the nasopharyn-
geal mucosa
12. Phenylephrine (a1 agonist) is used as a mydriatic
topical opthalmic ______________ agent to
facilitate fundoscopic examination of the
retina

13. ________ activation increases production of b2
aqueous humor in the eye, so blocking
________ receptors (timolol (non-selective
beta-blocker) eye drops) is a way of treat-
ing open-angle glaucoma (without the im-
paired accommodation caused by cholin-
ergic drugs like pilocarpine)
14. which adrenergic receptor controls vaso- α1 receptors (higher concentrations)
constriction?
15. which adrenergic receptor controls in- α1 receptors
crease blood pressure?
16. which adrenergic receptor controls mydri- α1 receptors
asis?
17. which adrenergic receptor controls re- α2 receptors
lease of ACh at presynaptic terminals?
