Posterior nasal spine

The medial end of the posterior border of the horizontal plate of palatine bone is sharp and pointed, and, when united with that of the opposite bone, forms a projecting process, the posterior nasal spine for the attachment of the musculus uvulae. It serves as a cephalometric landmark.
