The posterior boundary of the hard palate is formed by which bone?

The posterior boundary of the hard palate is formed by the horizontal plates of the palatine bones. The hard palate runs from the incisive foramen anteriorly to the posterior edge where the palatine bones meet, with the front two-thirds formed by the palatine processes of the maxilla and the back one-third completed by the horizontal plates of the palatine bones. The other bones don’t form this boundary: the ethmoid contributes to the nasal cavity and skull base, the maxilla provides the front portion, and the sphenoid lies more posteriorly and superiorly in the skull.
