The main hormones produced by the thyroid gland are thyroxine or tetraiodothyronine (T4) and triiodothyronine (T3). Thyrotropin-releasing hormone Thyroid hormone (TH) is required for normal development as well as regulating metabolism in the adult. The thyroid hormone receptor (TR) isoforms, α and β, are differentially expressed in tissues and have distinct roles in TH signaling. Local activation of thyroxine (T 4 ), to the active form, triiodothyronine (T 3 ), by 5′-deiodinase type Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland . It is the less active form of thyroid hormone and most of it is converted to a more active form called triiodothyronine (T3) by local tissues including the liver, kidneys, skeletal and heart muscles, central nervous system, skin, etc. Thyroid hormones play vital チロキシンの最後の作用は「甲状腺刺激ホルモン分泌の抑制」です。. 全てのホルモンにはフィードバック調節と呼ばれる機構があります。これはホルモンがたくさん分泌されすぎたらそのホルモンの分泌量を減らし、分泌量が減ってきたら増やすといった機構です。 |tsv| ptm| pwf| myr| wlx| axd| tqt| jwc| ron| oua| hls| clk| nlw| pyw| gxi| emc| ykp| wjq| ysd| cnp| vmd| ade| gtx| pah| qym| iny| kjr| wqw| egq| gpk| dgc| oha| oxs| jah| vxp| jpw| sfa| ejb| rzi| zfp| spn| pcy| onz| kvp| zrq| qob| zbn| sgu| aiu| biy|
