Development of Truncal and Bulbar Endocardial Cushions
Development of Truncal and Bulbar Endocardial Cushions Truncal Ridges Bulbar Ridges
Development of Truncal and Bulbar Endocardial Cushions Truncal Ridges Bulbar Ridges Truncal mesenchyme expands late in development as it depends on migration of mesenchyme from: -The ventral pharyngeal area -The pharyngeal arches -The endoderm
The ridges grow superiorly and inferiorly & fuse with the atrioventricular endocardial cushions and IV septum
The ridges grow superiorly and inferiorly & fuse with the atrioventricular endocardial cushions and IV septum Migration of cardiac neural crest from the pharyngeal arches contributes to division of the outflow tract
