Hard palate, epithelium and connective tissue

The upper surface of the hard palate faces the nasal cavity and is lined by pseudostratified columnar epithelium.
This type of epithelium characterizes the upper respiratory tract, including the mucosa of the trachea as well as the nasal cavity.
(Pseudostratified epithelium consists of both short and tall cells, all resting on the basement membrane.)  

The lower surface of the hard palate faces the oral cavity and is lined by stratified squamous epithelium.  This type of epithelium characterizes the upper gastrointestinal tract, including the mucosa of the esophagus as well as the oral cavity.

Between the nasal and oral mucosae of the palate is bone.
