1. Adrenocorticoicotropic delivering chemical (ARH) or corticotrophin
2. Development chemical delivering chemical (GHRH)

4. Development chemical inhibitory chemical (GHIH)
5. Gonadotropin-delivering chemical (GnRH)
6. Prolactin inhibitory chemical (PIH)
7. Prolactinrelasing chemical (PRH
8. MSH delivering chemical (MSHRH)
