Function [ edit ] The palatine velum is slightly raised by the levator veli palatini and made tense by the tensor veli palatini ; the palatopharyngeus muscles, by their contraction, pull the pharynx upward over the bolus of food and nearly come together, the uvula filling up the slight interval between them.
The levator veli palatini (/ l ɪ ˈ v eɪ t ər ˈ v iː l aɪ ˌ p æ l ə ˈ t aɪ n aɪ /) is a muscle of the soft palate and pharynx. It is innervated by the vagus nerve (cranial nerve X) via its pharyngeal plexus. During swallowing, it contracts, elevating the soft palate to help prevent food from entering the nasopharynx.
posterior: root of the pterygoid process and adjoining anterior surface of the greater wing of sphenoid bone; medial: perpendicular plate of the palatine bone and its orbital and sphenoidal processes; lateral: pterygomaxillary fissure; inferior: part of the floor is formed by the pyramidal process of the palatine bone.
Palatal petechiae. Petechiae on the soft palate are mainly associated with streptococcal pharyngitis, [6] and as such it is an uncommon but highly specific finding. [7] 10 to 30 percent of palatal petechiae cases are estimated to be caused by suction, which can be habitual or secondary to fellatio. [8]
Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep ...
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 greater palatine foramen is, along with the lesser palatine foramen, one of two foramina (holes) in each of the left and right palatine bones which form the posterior roof of the human mouth, known as the palate. It is sometimes known as the major palatine foramen.
A few fibers of palatopharyngeus muscle sweep backward under cover of the Passavant's ridge and form a U-shaped sling of palatopharyngeal sphincter. When the soft palate is elevated it comes in contact with ridge, the two together closing pharyngeal isthmus between nasopharynx and oropharynx. [2]
