Explanation

Adrenal or suprarenal gland (Gland of emergency) are paired structures located above the kidney. Each gland consists of outer cortex and inner medulla. Adrenal cortex is derived from mesoderm and release mineralocorticoids ($e.g.,$ aldosterone), glucocorticoids ($e.g.,$ cortisol) and sex corticoids ($e.g.,$ male sex hormone androgens and female oestrogen) hormones whereas adrenal medulla develops from neuro-ectoderm of embryo and releases nor-epinephrine (noradrenaline) and epinephrine (adrenaline) hormones.
