Hyperkalemia stimulates aldosterone secretion by depolarization of the zona glomerulosa cells
and hypokalemia inhibits such depolarization.

In normal physiology, zona glomerulosa cells
are typically hyperpolarized because of predominant potassium conductance, primarily mediated by K+ channels (A).
The histological data of myelolipoma associated with primary hyperaldosteronism showed high plasma aldosterone, hypokalemia and suppressed plasma renin activity; the histological study showed a myelolipoma with hyperplasia of glomerulosa cells
Several investigators have suggested that major physiological stimulation of aldosterone production by the adrenal zona glomerulosa cells
, angiotensin II and potassium, are to a varying degree dependant on extracellur calcium influx to achieve maximum stimulation [18, 19].
