Lacrimal bone

The lacrimal bone, os lacrimale, is a paired, quadrilateral plate (Fig. 48B) located in the anterior part of the medial orbital wall. It articulates with neighboring bones via the frontolacrimal, lacrimalorethmoidal, lacrimomaxillary, and lacrimoconchal sutures. The bone covers the anterior ethmoidal air Cells and features a posterior lacrimal crest, crista lacrimalis posterior, on its lateral surface. This crest terminates in a projection known as the lacrimal hamulus, hamulus lacrimalis. The posterior part of the bone contains the lacrimal groove, sulcus lacrimalis, which contributes to The formation of the nasolacrimal canal, canalis nasolacrimalis. Together with the corresponding groove on the frontal process of the Maxilla, this groove forms the fossa for the lacrimal sac, fossa sacci lacrimalis.

Ossification. An ossification center appears during the 3rd month of prenatal development within the Connective Tissue surrounding the Cartilage of the nasal capsule.
