Question

Quizplus · Accepted Answer

Catecholamines, such as epinephrine and norepinephrine, are important in the maintenance of blood pressure. They activate the sympathetic nervous system, which increases heart rate and contractility, constricts blood vessels, and mobilizes glucose for energy. They are secreted by the adrenal medulla, not the adrenal cortex. They do not reinforce the parasympathetic nervous system, and in fact, have the opposite effect. They promote glycogen breakdown and release of glucose into the bloodstream, not storage.
