Amnion chorion yolksac allantois
The amniotic sac is the sac in which the fetus develops in amniotes. Its wall is the amnion, the inner of the two fetal membranes. It encloses the amniotic cavity and the embryo.
The cotyledon protects the embryo
The protective structure that forms around a human embryo is called the amniotic sac or amnion. This sac contains amniotic fluid, which cushions and protects the developing embryo during pregnancy.
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
Membranes are organs formed by the combination of epithelial tissue and connective tissue. Epithelial tissue forms the protective outer layer, while connective tissue provides support and structure. Together, these tissues make up the various membranes found in the body, such as mucous membranes and serous membranes.

Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
The amniotic sac forms during the embryonic stage of development, around week 2 after fertilization. It is a protective membrane filled with amniotic fluid that surrounds and cushions the developing embryo/fetus in the uterus.
Tonsils
The amniotic sac forms during the early stages of embryonic development, specifically in the second week after fertilization. It develops from the amniotic ectoderm and surrounds the embryo, providing a protective environment filled with amniotic fluid. This fluid cushions the embryo and allows for movement, which is crucial for musculoskeletal development. The formation of the amniotic sac is an essential step in the establishment of a safe and supportive environment for the growing fetus.
