Although the terminology of "stress" is rather confusing, effects of certain kinds of stress stimuli (emotional stress, physical stress etc.) on [1] the secretion of catecholamines from the adrenal medulla are reviewed first. In the next sections, discussion is focused on the effect of stress on [2] biosynthesis and [3] the reuptake of catecholamines. Stress effects on [4] enkephalin metabolism in the adrenal medulla and [5] the possible roles of neuropeptides in the medulla under stress are also discussed. In conclusion, stress increases the secretion of catecholamines from the adrenal medulla and consequently levels of peripheral catecholamines, due to enhanced catecholamines synthesis, and decreased reuptake and degradation. One possible role of neuropeptides under stress is to modulate catecholamines secretion from chromaffin cells.}, pages = {47--58}, title = {Adrenal Chromaffin Cells and Stress}, volume = {40}, year = {1992} }
