Solution:

The adrenal cortex is derived from mesoderm and it produces glucocorticoids, mineralocorticoids and androgens which are steroid hormones. The adrenal medulla is derived from ectoderm and it produces epinephrine and norepinephrine which are catecholamines. The pancreas is derived from endoderm and it produces insulin and glucagon which are peptide hormones. The parathyroid gland is derived from endoderm and it produces a polypeptide hormone called parathormone or Collip's hormone.
