Question

Quizplus · Accepted Answer

Epinephrine and norepinephrine are both neurotransmitters released by the sympathetic nervous system to activate the fight or flight response in the body. They bind to adrenergic receptors on target cells, such as the heart, blood vessels, and lungs, to increase heart rate, contractility, and bronchodilation, among other effects. By binding to these receptors, epinephrine and norepinephrine can prolong and enhance the effects of the sympathetic nervous system.
