EMB 1 Formation of the body cavity Flashcards
Weeks for embryonic development?
What stages of growth do they go through?
What happens in week 4
What planes does folding of the embryo occur in?
Median plane (longitudinal)
Horizontal plane
Early vs late 4th week and the septum transversum?
why does this change happen?
Longitudinal folding
generally what happens?
- nerual fold on top of Notochord.
- the notochord expands while nerual fold material above it enlarges
- head fold and tail fold grow over ends
- a foregut, midgut, and hindgut are formed
Horizontal folding leads to formation of what?
intraembryonic coelom and encompass the midgut
Ectopia cordis
What gives rise to the parietal pleura?
What gives rise to the Visceral pleura?
Parietal pleura= Somatic layer of the lateral plate
Visceral pleura= Splanchnic layer of the lateral plate
What cavity is the heart in?
the lungs?
the abdomen?
What is the pericardioperitoneal canals?
Formation of the pleural and pericardial cavities
Pericardial cavity seprated from what by what?
Lungs develop where?
Pleuropericardial folds
goes to the formation of what?
How do these formations come to be?
formation of the pleural-peritoneal membrane
Closure of pericardioperitoneal canal
In the formation of diaphragm what do the highlighted structures turn into?
