b. peripheral tvasoconstriction
c. constriction tof tbronchial tsmooth tmuscle
d. increased tforce tof tmyocardial tcontraction
ANSWER: t B
Alpha1 treceptors tare tfound tin tthe teyes, tblood tvessels, tbladder, tand tmale treproductive
torgans.tStimulation tof talpha1 treceptor tsites tresults tin tconstriction.
OBJ: t Compare tand tcontrast tthe teffects tof tsympathetic tand tparasympathetic tstimulation tof tthe
theart.
