Adrenal Medullary Hormones. Cells in the adrenal medulla synthesize and secrete epinephrine and norepinephrine. The ratio of these two catecholamines differs considerably among species: in humans, cats and chickens, roughly 80, 60 and 30% of the catecholamine output is epinephrine. Following release into blood, these hormones bind adrenergic receptors on target cells, where they induce essentially the same effects as direct sympathetic nervous stimulation.
