Its medial end is sharp and pointed, and, when united with that of the opposite bone, forms a projecting process, the posterior nasal spine for the attachment of the musculus uvulae. The lateral border is united with the lower margin of the perpendicular plate, and is grooved by the lower end of the greater palatine canal.
The two horizontal plates articulate with each other at the posterior part of the median palatine suture and more anteriorly with the maxillae at the transverse palatine suture. [3] The human palatine articulates with six bones: the sphenoid, ethmoid, maxilla, inferior nasal concha, vomer and opposite palatine.
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 hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest. It is the most important bone in the midface. It provides structural support for the ...
The posterior nasal spine is part of the horizontal plate of the palatine bone of the skull. It is found at the medial end of its posterior border. It is paired with the corresponding palatine bone to form a solid spine. It is the attachment of the uvula muscle.
The floor of the nose is made up of the incisive bone and the horizontal plates of the palatine bones, and this makes up the hard palate of the roof of the mouth. The two horizontal plates join at the midline and form the posterior nasal spine that gives attachment to the musculus uvulae in the uvula.
Inferiorly, the muscle converges to form a tendon of attachment. This tendon winds medially around the pterygoid hamulus (with a small bursa interposed between the two) to insert into the palatine aponeurosis and into the bony surface posterior to the palatine crest of the horizontal plate of palatine bone.
