Metamorphosis is characterized by continued growth, particularly of the limbs, and the initiation of minor metabolic changes. These events are caused by the developing thyroid gland and the sensitivity of these tissues. thyroid hormones are secreted. During metamorphic development, metamorphic changes appear, because the concentrations of the hormones involved in metamorphosis change significantly compared to the previous premetamorphic stage. During the metamorphosis stage, the concentrations of these hormones differ within the substages of these stages. Early metamorphosis and late prometamorphosis are the names given to the substages of metamorphosis. Metamorphosis in anurans is initiated chemically by the decline (descriptive word) of prolactin, as mentioned previously, the antagonistic action of prolactin on thyroid secretory hormone (TSH) and also that TSH influences the secretion of thyroid hormones , Triiodothyronine (T3) Thyroxine (T4), which are responsible for metamorphic changes....
