Descriptor membranas extraembrionarias
Scope note: Finas capas de tejidos que rodean al embrión en desarrollo. En los VERTEBRADOS, como los REPTILES, AVES y MAMIFEROS, hay cuatro membranas extraembrionarias. Éstas son el SACO VITELINO, el ALANTOIDES, el AMNIOS y el CORION. Esas membranas proporcionan protección y medio de trasporte de nutrientes y residuos.

Scope note: 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.

Scope note 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.
