Resource summary

Hypothalamus
  1. Anterior Pituitary
    1. Growth hormone
      1. Promotes growth of the entire body by affecting protein formation, cell multiplication and cell differentiation
      2. Adrenocorticotropin hormone (ACTH or corticotropin): controls secretion of some of the adrenal cortical hormones (primarily glucocorticoids)
        1. TSH (thyrotropin): controls the rate of secretion of thyroxine and triiodothyronine by the thyroid gland. Control intracellular reaction rates
          1. Prolactin: promotes mammary gland development and milk production
            1. Gonadotropic hormones: FSH and LH which control growth of , hormonal and reproductive activities of the testis and ovaries
            2. Posterior pituitary
              1. ADH (Vasopressin): controls the rate of water excretion in the collecting ducts of the kidney
                1. Oxytocin: helps promote milk excretion from the mammary glands during breast feeding and also contractions during labour
                2. Hormones secreted by the hypothalamus
                  1. Thyrotropin-releasing hormone (TRH)
                    1. paraventricular nucleus
                    2. Gonadotropin-releasing hormone (GnRH)
                      1. ventromedial nucleus
                      2. Corticotropin-releasing hormone (CRH)
                        1. paraventricular nucleus
                        2. Growth-hormone releasing hormone GHRH
                          1. arcuate nucleus
                          2. Growth-hormone inhibitory hormone (somatostatin)
                            1. periventricular nucleus
                            2. Prolactin-inhibiting hormone (dopamine)
                              1. arcuate nucleus
