n. a type of receptor situated on the membrane of nerve cells. Closely associated with the sympathetic nervous system, this receptor binds norepinephrine, stimulating the heart and causing it to beat stronger and faster. It also helps relax smooth muscles and dilate blood vessels. Also called beta adrenergic receptor. Compare alpha adrenoreceptor.

BETA ADRENORECEPTOR: "A beta adrenoreceptor contrbutes to sympathetic activities such as vasodilation and increased heart rate."
