The intraembryonic coelom (or somatic coelom) is a a portion of the conceptus forming in the mesoderm. During the second week of development, the intermediate mesoderm splits into a dorsal somatic mesoderm (somatopleure) and a ventral splanchnic mesoderm (splanchnopleure). The resulting cavity between the somatopleure and splanchnopleure is called the intraembryonic coelom. This space will give rise to the thoracic and abdominal cavities.
It briefly has a connection with the extraembryonic coelom.
