The lacrimal bone (os lacrimale) is paired, forming the anterior part of the medial wall of the orbit. From below and from the front it is connected with the frontal process of the upper jaw, at the back - with the orbital plate of the latticed bone. Above, the teardrop border on the medial edge of the orbital part of the frontal bone. On the lateral surface of the bone there is a posterior lacrimal crest (crista lacrimalis posterior). Anterior to the lacrimal crest is a tear sulcus (sulcus lacrimalis), which together with the eponymous furrow of the upper jaw forms a fossa lacrimalis fossa (fossa lacrimalis).
