Anatomy and Histology of Palate

         Amin Abusallamah
Anatomy Palate
Introduction
• The roof of the oral cavity consists of the
  palate, which has two parts-an anterior hard
  palate and a posterior soft palate.
Hard palate
• The hard palate separates the oral cavity from
  the nasal cavities. It consists of a bony plate
  covered above and below by mucosa:
• Above, it is covered by respiratory mucosa and forms
  the floor of the nasal cavities;

• Below , it is covered by a tightly bound layer of oral
  mucosa and forms much of the roof of the oral cavity
Soft palate
• The soft palate continues posteriorly from the
  hard palate and acts as a valve that can be:

• depressed to help close the oropharyngeal isthmus;
  elevated to separate the nasopharynx from the
  oropharynx.
Blood and nerves supply

Veins from the palate
generally follow the arteries
and ultimately drain into the
pterygoid plexus of veins in
the infratemporal fossa
Histology of Palate
Palatal mucosa
• the palate is covered by a thick stratified squamous epithelium
  Ep supported by densely collagenous lamina propria L.
• The mucosa of the hard palate is bound down to the
  underlying bone B by relatively dense submucosal tissue S
  containing a few accessory salivary glands.
