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

Thick mucosa

keratinised stratified squamous epithelium

Species Differences

Herbivores

More heavily keratinised

Feline

Short hard palate
