Palatal formation
WebFormation of the secondary palate requires the palatal shelves to undergo a process called shelf elevation or shelf reorientation, in which the palate shelves move from lateral of the tongue to above the dorsum of the tongue and change their orientation in the oral-nasal cavity from vertical to horizontal. WebFeb 15, 2011 · In this report, we show that the Bmpr1a gene, encoding a type I receptor for bone morphogenetic proteins (Bmp), is preferentially expressed in the primary palate and anterior secondary palate during palatal outgrowth. Following palatal fusion, Bmpr1a mRNA expression was upregulated in the condensed mesenchyme progenitors of palatal bone.
