| − | The hard palate ('''palatum durum''') forms the rostral roof of the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]]. It merges caudally with the [[Soft Palate|soft palate]] where a connective tissue '''aponeurosis''' replaces the bone.

| − | The hard palate is the bony shelf of the palatine processes of the [[Skull and Facial Muscles - Anatomy & Physiology#Incisive Bone (os incisivium)|incisive]], [[Skull and Facial Muscles - Anatomy & Physiology#Maxilla|maxillary]] and [[Skull and Facial Muscles - Anatomy & Physiology#Paltine Bone (os palatinium)|palatine bones]]. Failure of the [[Skull and Facial Muscles - Anatomy & Physiology#Palatine Bone (os palatinium)|palatine bones]] to fuse results in [[Cleft Palate|cleft palate]].
| |
| − | There are 6-8 fixed transverse ridges to direct food caudally. The hard palate is flat and has '''incisive papilla''' (small median swelling) behind the incisive [[:Category:Teeth - Anatomy & Physiology|teeth]] and smaller '''papillae ducts''' branching to the [[Nasal Cavity - Anatomy & Physiology|nasal cavity]] and vomeronasal organ.
