▶️ name the some extra embryogenic membrane ❓
▶️ when do morphogenetic movement take place ❓


​

Answer 1

Answer:

Hey mate ✌️✌️

Explanation:

Some extra embryogenic membrane are:-

➡️Amnion

➡️Yolk sac

➡️Allantois

➡️Choriom

Morphogenetic movement:-

(A) Morphogenetic movement in the early embryo takes place mainly through the movement and deformation of the epithelial cells, which constitute the embryo, and includes: a) invagination movement of epithelium, b) extension movement caused by rearrangement of epithelial cells, and c) locomotive movement (migration) of epithelial tissues.

(B) Examples of morphogenetic movement in amphibians and mammalian embryos. The cells move in the directions of the red arrows shown in the diagram. a) Gastrulation of the frog embryo: the mesoderm and endoderm move into the interior of the embryo through invagination and extension movements and form an inner lining of the ectoderm. b) Gastrulation of the mammalian embryo: cells separate from the central part of the ectoderm and move into the interior of the embryo, and become endoderm and mesodermal cells. In the mammalian embryo, the archenteron is not actually formed at this time, but this morphogenetic movement is called gastrulation.

✍️kinds of extraembryonic membranes to protect the embryo:

• amnion
• amnion yolk sac
• amnion yolk sacallantois
• amnion yolk sacallantoisand chorion

✍️Morphogenetic movement consists of several basic cellular deformations and movements, including the invagination movement, in which contraction of one side of the embryo causes bending and encourages epithelial cells to extend inward into the embryo, the extension movement caused by the rearrangement of epithelial .
