Ans. is `d i.e., AndrogensThe adrenal coex is divided into three zones (outer to inner) : Zona glomerulosa, zona fasciculata and zona reticularis.All three coical zones secrete coicosterone, but the active enzymatic mechanism for aldosterone biosynthesis is limited to the zona glomerulosa whereas the enzymatic machanisms for forming coisol and sex hormones are found in the two inner zones. Fuhermore, subspecialization occurs within the inner two zones, the zona fasciculata, secreting mostly glucocoicoids and the zona reticularis secreting mainly sex hormones.
