May present initially with symptoms of myocardial ischemia. The zona reticularis produces sex hormones. Aldosterone causes sodium and water retention.
Epinephrine is the precursor of norepinephrine. Tyrosine is the precursor for catecholamines. The zona fasciculata produces androgens. The zona glomerulosa produces aldosterone. The cortex produces mainly catecholamines.
