The hard palate comprises about two-thirds of the total palate surface area, and its underlying bony structure consists of the palatine processes of the maxilla and the horizontal plates of the palatine bones.
What is the posterior part of the palate made of?
soft palate, also called palatal velum, velum, or muscular palate, in mammals, structure consisting of muscle and connective tissue that forms the roof of the posterior (rear) portion of the oral cavity.
Which two bones join to form the posterior part of the hard palate?
The plates from the right and left palatine bones join together at the midline to form the posterior quarter of the hard palate (see Figure 6a). Thus, the palatine bones are best seen in an inferior view of the skull and hard palate.
What Innervates the hard palate?
The greater palatine and nasopalatine nerves both branches of the maxillary nerve innervate the hard palate, whereas the lesser palatine branch of the maxillary nerve supplies the soft palate.
How is the hard palate formed?
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.
What is hard palate?
The hard palate is a horizontal bony plate that forms a subsection of the palate of the mouth. It forms the anterior two-thirds of the roof of the oral cavity. The hard palate is comprised of two facial bones: the palatine process of the maxilla and the paired palatine bones.
Which bones form the hard palate quizlet?

What is hard palate and soft palate?
The roof of the mouth is known as the palate. The hard palate is the front part of the roof of the mouth, and the soft palate is the back part.
Which two bones join to form the posterior part of the hard palate quizlet?
*Palatine bones- form the posterior part of the hard palate. *Transverse palatine suture- is suture between the maxilla & the palatine bone.
What bone is the posterior roof of mouth?
Maxilla – The maxilla is the bone into which the upper row of teeth is set, and it forms the roof of the mouth. It also creates the most medial aspects of the cheekbones. Zygomatic bone – This bone forms the lateral and posterior component of the cheekbones; it is the most curved portion.
What bones landmarks and sutures form the hard palate?
The hard palate is made up of four cranial bones: the paired maxillae and the paired palatine bones. The maxillae are situated anteriorly and cover the majority of the area between the two sides of the dental arch. Medially, the maxillae articulate to one another via the anterior median palatine suture.
Where are the hard palate?
The front, bony part of the roof of the mouth.
What is above the hard palate?
The soft palate is the muscular part at the back of the roof of the mouth. It sits behind the hard palate, which is the bony part of the roof of the mouth.
Why is the hard palate hard?
This layer forms several ridges that help grip food while the tongue agitates it during chewing. The hard palate provides space for the tongue to move freely and supplies a rigid floor to the nasal cavity so that pressures within the mouth do not close off the nasal passage.
