The L-shaped palatine bones are located behind the maxillae (see Figure 1). The horizontal portions form the posterior section of the hard palate and the floor of the nasal cavity. The palate’s function is to separate the nasal cavity from the oral cavity, enabling you to continue breathing while chewing.
What is the palate?
The palate (also known as the ‘roof of the mouth’), forms a division between the nasal and oral cavities. It is separated into two distinct parts: Hard palate – comprised of bone. It is immobile. Soft palate – comprised of muscle fibres covered by a mucous membrane.
What are the two parts of the soft palate?
It is separated into two distinct parts: Hard palate – comprised of bone. It is immobile. Soft palate – comprised of muscle fibres covered by a mucous membrane. It can be elevated to close the pharyngeal isthmus during swallowing – this prevents the food bolus from entering the nasopharynx.
What is a cleft lip?
Cleft lip – occurs when the medial nasal prominence and maxillary prominence fail to fuse. Cleft palate – can occur in isolation when the palatal shelves fail to fuse in the midline, or in combination with cleft lip. Cleft lip and cleft palate are relatively common, occurring in approximately 1/1000 births.
Where does the palate receive arterial supply?
Vasculature. The palate receives arterial supply primarily from the greater palatine arteries, which run anteriorly from the greater palatine foramen. In addition, the anastomosis between the lesser palatine artery and ascending palatine artery provide collateral supply to the palate.
What is the posterior border of the soft palate?
The posterior border of the soft palate is free (i.e. not connected to any structure), and has a central process that hangs from the midline - the uvula. The soft palate also forms the roof of the fauces ; an area connecting the oral cavity and the pharynx.
Which surface of the palate has a mucosal lining?
Reflecting this, the superior and inferior palatal surfaces have different mucosal linings: Superior aspect of palate (nasal cavity) - respiratory epithelium. Inferiorly aspect of palate (oral cavity) - oral mucosa, populated by secretory salivary glands. The hard palate forms the anterior aspect of the palate.
Which structure divides the nasal cavity and the oral cavity?
Structure. The palate divides the nasal cavity and the oral cavity, with the hard palate positioned anteriorly and the soft palate posteriorly. It forms both the roof of the mouth and the floor of the nasal cavity.

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. 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 high-front vowels, palatal consonants, and retroflex consonants such as [i] like "s ee ", [j] like " y es", [ç] (realization of /hj/ in English) like " h ue", and [ɻ] (/r/, only for some speakers) like " r ed".
What is the hard palate?
The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone. It forms a partition between the nasal passages and the mouth. On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help facilitate the movement of food backward towards the larynx.
