Details Artery greater palatine artery Nerve greater palatine nerve, nasopalatine nerve Identifiers Latin palatum durum MeSH D021362 TA A05. 1.01. 103 FMA 55023 Anatomical terminology ( edit on Wikidata ) The hard palate is a thin horizontal bony plate of the skull, located in the roof of the mouth. It is formed by the palatine process of the maxilla and horizontal plate of palatine bone, and spans the arch formed by the upper teeth.

It forms a partition between the nasal passages and the mouth. On the anterior portion of the roof of the hard palate are the plicae, irregular ridges in the mucous membrane that help facilitate the movement of food backwards towards the larynx. This partition is continued deeper into the mouth by a fleshy extension called the soft palate. Function The hard palate is important for feeding and speech. Mammals with a defective hard palate may die shortly after birth due to inability to suckle ( see Cleft palate below ). It is also involved in mastication in many species. The interaction between the tongue and the hard palate is essential in the formation of certain speech sounds, notably palatal consonants such as / j / and / ɟ /. Clinical significance Cleft palate In the birth defect called cleft 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 is cleft lip ). While cleft palate has a severe impact upon the ability to nurse and speak, it is now successfully treated through reconstructive surgical procedures at an early age, where such procedures are available. Palatal abscesses The proximity of the dento - alveolar process explains the forming of palatal abscesses and the palatal mucosa and submucosa with its numerous glands and the squamous keratinized epithelium is in correlation with the rich tumoral pathology.
