Examine the hard palate [frontal section] which separates the oral cavity from the nasal cavity. The hard palate forms approximately two-thirds of the palate anteriorly. It is formed by the palatine processes of the maxillary bones [cross-section] and horizontal plates of the palatine bones [cross-section]. The mucosal lining of the hard palate is innervated by branches of the greater palatine nerve. They enter the region of the hard palate via the greater palatine canal [cross-section]. The nasopalatine nerve enters the hard palate region via the incisive canal [cross-section].
