A tumor type of this non-skin organ was classically described by the “rule of 10s.” Harvey, Kirsten, and a proto-oncogene named after a malignancy most often found in this organ comprise the human Ras genes. Greater amplification of the N-myc gene correlates with a worse prognosis for that pediatric tumor in this organ (-5[1])and often corresponds to increased levels of homovanillic acid. (-5[1])MIBG accumulates in cells in this organ that share an affinity for chromium salt staining with similarly named (*) serotonin-secreting “entero” cells in the GI tract. Pheochromocytomas originating from this organ's chromaffin cells (-5[1])can paroxysmally secrete high levels of catecholamines. This organ’s cortex secretes glucocorticoid (-5[1])hormones, including cortisol. (-5[1])For 10 points, name this paired organ whose medulla produces (-5[1])the majority of epinephrine. ■END■ (10[2]0[2])
