The hard palate is a thin horizontal bony plate of theskull , located in the roof of the mouth. It spans the arch formed by the upperteeth .It is formed by the
palatine process of the maxilla andhorizontal plate of palatine bone .It forms a partition between the nasal passages and the
mouth . This partition is continued deeper into the mouth by a fleshy extension called thesoft palate .Function
The interaction between the
tongue and the hard palate is essential in the formation of certain speech sounds, notably /t/, /d/, /c/, and /IPA|ɟ/.Cleft
In the
birth defect calledcleft palate , the left and right portions of this plate are not joined, forming a gap between the mouth and nasal passage (a related defect affecting the face iscleft lip ).Cleft palate has a severe impact upon the ability to nurse and speak but is now cured through reconstructive surgical procedures at an early age (where such procedures are available).
