(v) Hormones of Digestive system. Gastrin, secretin, enterocrinin etc.

  • Triple F Glands. Emergency glands or adrenals for flight, fight and fright.
  • Four S Glands. Adrenal glands as they manage salt, sugar, sex and stress reactions.
  • Gonadotrophins, FSH and LH/ICSH. Some workers also include hCG and prolactin under gonadotrophins.
