Stress-triggered changes in the adrenal medullary cells structure and function in the rat

ABSTRACT

Objective: Previous authors provided electrophysiological evidence for selective activation of epinephrine or norepinephrine-secreting adrenal chromaffin cells. However, the corresponding histological changes in the adrenal chromaffin cells were not described. To provide histological and biochemical evidence that different sympathetic preganglionic neurons regulate epinephrine and norepinephrine secretion
