Endocardial cushion development
(truncal and bulbar)
bulbar ridges
truncal ridges
Endocardial cushion development
(truncal and bulbar)
bulbar ridges
truncal ridges
Truncal mesenchyme expands due to migration from: ventral pharyngeal area, pharyngeal arches and endoderm
Both ridges grow superiorly and inferiorly then fuse with the atrioventricular endocardial cushions and the intraventricular septum
Cardiac neural crest migration from pharyngeal arches contributes to division of the outflow tract
Both ridges grow superiorly and inferiorly then fuse with the atrioventricular endocardial cushions and the intraventricular septum
Both ridges grow superiorly and inferiorly then fuse with the atrioventricular endocardial cushions and the intraventricular septum
Both ridges grow superiorly and inferiorly then fuse with the atrioventricular endocardial cushions and the intraventricular septum
Both ridges grow superiorly and inferiorly then fuse with the atrioventricular endocardial cushions and the intraventricular septum
