Role of Hormones in Metamorphosis of Frog
Hormonal regulation in frogs is responsible for the changes that occur during metamorphosis. The role of various hormone in growth and development of frog is explained below:
Thyroid Hormones
The thyroid glands of frogs are located between their eyes and undergo various morphological changes during metamorphosis. The thyroid gland secretes thyroxine (T4) and triiodothyronine (T3) hormones during metamorphosis. Thyroxine is produced by the thyroid gland and secreted into the bloodstream.
- Thyroid hormones help in the differentiation of tissues and organs during metamorphosis. It plays a role in the transition from aquatic tadpole to terrestrial frog.
- Thyroid hormone promote the resorption of the tadpole’s tail, an important step in metamorphosis. It play an important role in the development of hind limbs and transition to a fully functional frog.
Gonadotropin-Releasing Hormone
Gonadotropin-Releasing Hormone is produced in the hypothalamus, and acts on the pituitary gland to release gonadotropins. Gonadotropin-Releasing Hormone in frogs stimulates gonadal development and regulates reproductive behaviors. GnRH secretion is influenced by environmental and seasonal variations, coordinating with reproductive cycles.

Role of Hormones in Completing the Life History of Insects and Frogs
The role of hormones in completing the life history of insects and frogs involves regulating developmental stages such as metamorphosis, growth, reproduction, and behaviour. The hormones are chemical messengers that play an important role in the life cycle of insects and frogs.
In frogs, the hormone thyroxine is responsible for metamorphosis whereas in insects, ecdysone and juvenile hormones are needed. These hormones are produced in small quantities but are essential for the completion of the life cycle of insects and frogs. In this article, we will study the role of hormones in completing the life cycle of insects and frogs.
