The extraembryonic coelom is a portion of the conceptus consisting of a cavity between Heuser's membrane and the hypoblast.

It divides the two layers of extraembryonic mesoderm (splanchnopleuric and somatopleuric).

It is also known as the "chorionic cavity". [ [http://sprojects.mmip.mcgill.ca/embryology/earlydev/week2/week2.html week2 ] ]
