Metamorphosis in Amphibians(Part-2) || Thyroid Hormone Signaling | Developmental Biology

TOPIC: Metamorphosis in Amphibians(Part-2) || Thyroid Hormone Signaling || Developmental Biology || CSIR NET 2024 Amphibian metamorphosis is associated with morphological changes that prepare an aquatic organism for a primarily terrestrial existence. In urodeles (salamanders), these changes include the resorption of the tail fin, the destruction of the external gills, and a change in skin structure. In anurans (frogs and toads), the changes are more dramatic, with almost every organ subject to modification. The changes in amphibian metamorphosis are initiated by thyroid hormones such as thyroxine (T4) and tri-iodothyronine (T3) that travel through the blood to reach all the organs of the larva. When the larval organs encounter these thyroid hormones, they can respond in any of four ways: Growth (as in the hindlimbs of the frog), Death (as in the tail of the frog), Remodeling (as in the frog’s intestine), and Respecification (as in the liver enzymes of the frog). #csirnet2024 #CSIR2024 #csirnetlectures #csirnet ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 💡Telegram channel link: https://telegram.me/jyotikumariTP 💡Facebook page-   / teaching.pathshala   💡Instagram ID: https://www.instagram.com/teaching.pa... ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ABOUT TEACHING PATHSHALA🧬 --- This channel will have the syllabus wise lectures Video for CSIR-NET-Lifescience/GATE-Lifescience/BARC/ICMR-JRF/ICAR. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🧪Another channel (Science Kaksha) for Basics (NEET,12th, 11th, 10th,9th, 8th science) subscribe:    / @sciencekakshajyotikumari   ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ IMPORTANT PLAYLIST LINK: ✔️Master CLasses Series:    • Master Classes (For all Exams)   ✔️Immunology Lectures:    • Immunology-for College , Competitive Exams...   ✔️ GATE -XL:    • Плейлист   ✔️Plant secondary metabolites:    • PLANT SECONDARY METABOLITES- CSIR NET (PLA...   ✔️Developmental Biology:    • Development Biology   ✔️Plant Physiology:    • Plant Physiology/ Botany   ✔️Ecology:    • Ecology & Environment   ✔️Evolution:    • EVOLUTION   ✔️ICMR-JRF:    • Плейлист   THANK YOU!!
