Anterior-pituitary hormones {growth hormone}| (GH) can increase bone, increase body growth, raise metabolism rate, and make glucose from glycogen. Growth hormones enter cells directly and bind to cytoplasm receptors, which send molecules to cell nucleus to bind to DNA sites and express or repress genes. Growth hormone helps generate and maintain nerve-pathway connections.
Hormones {trophic hormone} can generate and maintain nerve-pathway connections.
Anterior-pituitary hormones {thyrotropin}| can increase thyroid growth and thyroxin production.
Hypothalamus and anterior-pituitary hormones {thyrotropin-releasing hormone}| (TRH) can act locally to release thyrotropin. Small quantities induce euphoric states and can be antidepressants for treating affective disorders. Medulla-oblongata hormones can release hypothalamus thyrotropin.
Thyroid hormones {thyroxin}| can increase basal metabolism rate. Thyroxin requires iodine.
