Gross Anatomy Digestive Embryology

Front 1

what is the primordium of the embryonic body cavities?

Back 1

intraembryonic coelom

Front 2

when does the intraembryonic coelom begin to develop?

Back 2

near the end of week 3

Front 3

in the horseshoe shape of the intraembryonic coelom, what is represented by the curve and the lateral limbs?

Back 3

curve - future pericardial cavity

lateral limbs - future pleural and peritoneal cavities

Front 4

when does the embryonic disc fold?

Back 4

week 4

Front 5

when are the lateral parts of the intraembryonic coelom brought together?

Back 5

week 4

during folding of embryonic disc

Front 6

what happens when the caudal part of the ventral mesentery disppears?

Back 6

right and left parts of intraembryonic coelom merge and form the peritoneal cavity

Front 7

what encloses the primitive gut and suspends it from dorsal body wall?

Back 7

splanchnic layer of mesoderm by a double-layered peritoneal membrane known as the dorsal mesentery

Front 8

until when does the embryonic pericardial cavity communicate with the peritoneal cavity?

Back 8

until week 7

via paired pericardioperitoneal canals

Front 9

when do partitions form at the cranial and caudal ends of pericardioperitoneal canals?

Back 9

week 5 and week 6

Front 10

what separates the pericardial cavity from the pleural cavities?

Back 10

fusion of cranial pleuropericardial membranes with mesoderm ventral to the esophagus
