Introduction

The hard palate (palatum durum) forms the rostral roof of the oral cavity. It merges caudally with the soft palate where a connective tissue aponeurosis replaces the bone.

Structure and Function

  • Bony shelf of palatine processes of the incisive, maxillary and palatine bones. Failure of the palatine bones to fuse results in cleft palate.
  • 6-8 fixed transverse ridges to direct food caudally
  • Flat
  • Incisive papilla (small median swelling) behind incisive teeth
  • Smaller papillae ducts branching to nasal cavity and vomeronasal organ

Histology
