Borders
Of the four borders:
- the anterior articulates with the frontal process of the maxilla;
- the posterior with the lamina papyracea of the ethmoid;
- the superior with the frontal bone.
- The inferior is divided by the lower edge of the posterior lacrimal crest into two parts:
- the posterior part articulates with the orbital plate of the maxilla;
- the anterior is prolonged downward as the descending process, which articulates with the lacrimal process of the inferior nasal concha, and assists in forming the canal for the nasolacrimal duct.
