Development of Body Cavities & Diaphragm - Coggle Diagram
Development of Body Cavities & Diaphragm
Mesoderm
Describe the development of lateral plate mesoderm, intra-embryonic coelom, cardiogenic mesoderm, and septum transversum
Describe the derivatives of the different portions of the lateral plate mesoderm, cardiogenic mesoderm, and septum transversum
Lateral Plate Mesoderm
Splanchnic portion
Cardiogenic Mesoderm
Septum Transversum
Somatic
Diaphragm Development
Describe the four sources that contribute to the formation of the diaphragm
Pleuroperitoneal membranes
Assess the portion of the diaphragm that is initially completed by the pleuroperitoneal membrane. Why does the ratio of contribution from the pleuroperitoneal membrane to the diaphragm decrease?
Esophageal Mesentary
Analyze the contribution of the dorsal mesentery of the esophagus. Which portion(s) of
the diaphragm develop from the dorsal mesentery of the esophagus?
Septum Transversum
Assess how the septum transversum is formed and how it contributes to the sources of
diaphragm formation
Lateral Body Wall
Assess the contribution from the lateral body wall. How does expansion of the pericardioperitoneal canals (pleural cavities) play a role in this contribution to the diaphragm and to the development of the costodiaphragmatic recesses?
Disorders of the Diaphragm
Analyze the underlying cause of congenital diaphragmatic hernia, the most common
location (and why), and the consequences of herniated abdominal contents within one of the pleural cavities
Body Cavity Partitioning
Describe the linings of the intra-embryonic coelom. How do they compare to the adult?
Assess how the pleuropericardial folds partition the intra-embryonic coelom. Which portions are separated? Is this a complete separation? Which areas of the intra- embryonic coelom can still communicate with each other?
Describe how expansion of the pericardioperitoneal canals ventrally contributes to the
formation of the fibrous pericardium
Pleuropericardial folds
Assess how the pleuroperitoneal membranes partition the intra-embryonic coelom. Which portions are separated? Is this a complete separation? Which areas of the intra- embryonic coelom can still communicate with each other?
Assess how the septum transversum partitions the intra-embryonic coelom. Which portions are separated? Is this a complete separation? Which areas of the intra- embryonic coelom can still communicate with each other?
Body Cavity Formation
Compare and contrast the body cavities in the adult and the initial body cavity that
forms in the embryo
Embryonic Folding
Assess the consequences of head, tail, and lateral folding
Head folding
Analyze the formation of the initial intra-embryonic coelom prior to head folding
Assess the consequences of head folding on the overall shape of the intra-embryonic
coelom and on the cranial loop specifically. What terms are utilized to describe the segments of the intra-embryonic coelom following head folding? What are the pericardioperitoneal canals related to?
Tail Folding
Lateral Folding
Assess the consequences of lateral folding especially within the peritoneal cavity and the overall shape of the intra-embryonic coelom
