The developmental stages of extraembryonic membranes in frog embryos are visually illustrated in a series of images. These images showcase the intricate processes involved in the formation of structures such as the amnion, chorion, yolk sac, and allantois, leading up to the development of the placenta. Detailed depictions of nephrotomal bands, sclerotome, and dermatome are also provided, shedding light on the embryonic development of frogs. Each image captures crucial aspects of embryonic growth, offering valuable insights into the intricate developmental biology of frog embryos.

  1. B.Bindu Bennet Assistant Professor, PG Department of Zoology Sarah Tucker College Tirunelveli

  2. INTESTINE IN FROG Each lateral plate splits into two layers of mesoderm The parietal or somatic mesoderm The visceral or splanchnic mesoderm The space between these two layers is the coelom.

  3. According to McEwen therefore are originally dorsal extension of the coelom. At this stage the coelom is double i.e one coelom on each side of the embryonic gut.

  4. THE NEPHROTOMAL BANDS

  5. THE SCLEROTOME

  6. THE DERMATOME

  7. DEVELOPMENT OF EXTRA EMBRYONIC MEMBRANES

  8. DEVELOPMENT OF YOLK SAC

  9. DEVELOPMENT OF AMINON AND CHORION

  10. DEVELOPMENT OF ALLANTOIS

  11. PLACENTA

  12. TYPES OF PLACENTA Four type of placenta : Cotyledonary placenta Zonary placenta Discoidal placenta Diffuse placenta

  13. COTYLEDONARY PLACENTA

  14. ZONARY PLACENTA

  15. DISCOIDAL PLACENTA

  16. DIFFUSE PLACENTA
