vomer

seperate bone: continuation of lamina perpendicularis to maxilla (dividing the nasal meatus)

os lacrimale

seperate bone: located between processus frontalis of maxilla os ethmoidalis and os frontalis. facies towards eyes

sulcus lacrimalis

os lacrimale: sulcus towards maxilla

canalis nasolacrimalis

canal formed by sulcus lacrimalis of processus frontalis (maxilla) and of sulcus lacrimalis (os lacrimalis)
