Blockade of a (alpha) adrenoceptors is likely to cause a reduction in

A. False Sweating is mediated by cholinergic nerves.

B. False Bronchial smooth muscle has few alpha receptors; beta blockade tends to cause bronchoconstriction.

C. False Stimulation of alpha or beta adrenoceptors inhibits the gut.

D. True Alpha receptors mediate vasoconstriction.

E. False The heart has few alpha receptors; beta receptor blockade slows the heart.
