Somatic Lateral Plate Mesoderm
Term
What connective tissue is derived from Somatopleura?
Definition
Parietal Pleura, Fibrous Pericardium, and Serous Parietal Pericardium
Term
What connective tissue is derived from Splachnopleura?
Definition
Visceral Pleura and Serous Visceral Pericardium
Term
Splachnopleura is derived from what?
Definition
Splanchnic Lateral Plate Mesoderm
Term
Where does the primordial heart initially develop?
Definition
splachnic lateral plate mesoderm, as the body folds the heart will end up ventral to the Gut Tube

Splachnic Lateral Plate Mesoderm
Term
Where does the diaphragm initally develop?
Definition
Somatic Lateral Plate Mesoderm
Term
The pleuralpericardial fold separates what from each other?
Definition
Developing space of the lungs and developing space of the heart
Term
Where do the pleuropericardial folds meet?
Definition
Dorsal mesentary of the esophagus
Term

Definition
Splachnic mesoderm
Term
Lungs develop as a diverticuli of what body structure?
Definition
esophagus
Term
What forms the central tendon of the diaphragm?
Definition
Septum Transversum. Bisects diaphragm and attaches to esophagus on the dorsal mesentary
Term
What are the pericardioperitoneal cavities?
Definition
transient openings between spaces of developing heart and longs
Term
The septum transversum is derived from what tissue?
Definition
somatic lateral plate mesoderm
Term
What are the pleuralperitoneal folds?
Definition
Folds that come together to close off the pleural cavity from the abdominal cavity. Complete the diaphragm
Term
What are pleuralperitoneal folds derived from?
Definition
somatic mesoderm
Term
What tissues compose the diaphragm?
Definition
Septum transversum (somatic mesoderm), dorsal mesentary (splachnic mesoderm), pleuralperitoneal folds (somatic mesoderm), and skeletal muscles (myotomes)
Term
