Enterocoely
Enterocoelom (adjective forms: enterocoelic and enterocoelous) describes both the process by which some animal
Etymology
The term enterocoely derives from the Ancient Greek words ἔντερον (énteron), meaning 'intestine', and κοιλία (koilía), meaning 'cavity'.[2][3] This refers to the fact that fluid-filled body cavities are formed from pockets related to the embryonic gut.
Taxonomic distribution
Enterocoely is the stage of embryological development of deuterostomes in which the coelom forms.[4] This type of coelom formation occurs in deuterostome animals, which for this reason are also known as enterocoelomates.
By contrast, in protostomes, the body cavity is often formed by schizocoely.[4]
Embryonic development
Enterocoelous development begins once the embryo reaches the
The stage of coelom formation starts with the gastrula; as the archenteron forms, pockets of migrating cells also form, creating another layer between the endoderm and ectoderm, the mesoderm. These pockets gradually expand to form the coelom.[5]
