Hormone List

HORMONE | Type | Found | |

Growth hormone (GH) | Protein | Anterior lobe of pituitary | DIRECT EFFECTS ARE: Bones and skeletal muscles / increased protein synthesis, encourages the use of fats for fuel INDIRECT EFFECTS ARE: Mediates growth via growth-promoting proteins – insulin-like growth factors (IGFs)REGULATED BY: hypothalamic hormones with antagonistic effects: Growth Hormone-Inhibiting Hormone (GHIH) & Growth Hormone-Releasing Hormone (GHRH)MECHANISM OF ACTION: PIP2-CA2+ second messenger system |

Thyroid-stimulating hormone (TSH) | Protein | Anterior lobe of pituitary | EFFECTS ARE: Stimulating the normal development and secretory activity of the thyroid gland. TRIGGERED BY: Hypothalamic peptide Thyrotropin-Releasing Hormone (TRH)INHIBITED BY: Rising blood levels of thyroid hormones / acts on both the pituitary and the hypothalamus (negative feedback)MECHANISM OF ACTION: cAMP second messenger system |

Adreno-corticotropic hormone (ACTH) | Protein | Anterior lobe of pituitary | TRIGGERED BY: Hypothalamic Corticotropin-Releasing Hormone (CRH) in a daily rhythm EFFECTS ARE: Promotion of glucocorticoids that help the body to resist stressorsMECHANISM OF ACTION: cAMP second messenger system |

Follicle-stimulating hormone (FSH) | Protein | Anterior lobe of pituitary | TRIGGERED BY: Hypothalamic Gonadotropin-Releasing Hormone (GnRH) during and after pubertyEFFECTS ARE: Stimulates gamete productionMECHANISM OF ACTION: cAMP second messenger system |

Luteinizing hormone (LH) | Protein | Anterior lobe of pituitary | TRIGGERED BY: Hypothalamic Gonadotropin-Releasing Hormone (GnRH) during and after pubertyEFFECTS ARE: Regulates the function of ovaries and testes MECHANISM OF ACTION: cAMP second messenger system |

Prolactin (PRL) | Protein | Anterior lobe of pituitary | TRIGGERED BY: SucklingEFFECTS ARE: stimulates milk production of the breast / suckling stimulates (PRL) release and continued milk production (Positive feedback)...
