Definitions
The thin layers of tissue that surround the developing embryo. There are four extra-embryonic membranes commonly found in VERTEBRATES, such as REPTILES; BIRDS; and MAMMALS. They are the YOLK SAC, the ALLANTOIS, the AMNION, and the CHORION. These membranes provide protection and means to transport nutrients and wastes. Extra-embryonic tissues that contain the FETUS during PREGNANCY. They provide the support to accommodate FETAL DEVELOPMENT. Depending on the species, their structure and complexity vary greatly in the different forms of PLACENTA. These membranes undergo rupture during PARTURITION.
