connects the Pericardial cavities cranially and the Peritoneal cavities caudally.
Where do the Pericardioperitoneal canals lie?
lateral to primitive foregut and dorsal to Septum transversum
Pleuropericardial folds (forms the pericardial sac) separates pericardial cavities from pleural cavities
Pleuroperitoneal folds are located inferior to the lungs
Which Pericardioperitoneal is larger?
The left Pericardioperitoneal canal is larger than the right
By when are both Pericardioperitoneal canals closed?
The Pleuropericardial folds enlarge to form partitions that separate the Pericardial cavity from the Pleural cavities. Inner layer forms the Fibrous pericardium
What components does the diaphragm develop from?
i) Septum transversum—gives rise to the Central tendon of Diaphragm ii) Pleuroperitoneal membranes iii) Dorsal mesentery of esophagus-gives rise to crura of Diaphragm iv) Lateral body walls (muscular ingrowths from the body wall)
