In front of the opening of the sinus is a deep lacrimal groove which the lacrimal bone and inferior nasal concha convert into the nasolacrimal canal, which transmits the nasolacrimal duct.
The " upper border " articulates with the frontal bone and the " anterior " with the nasal; the " posterior border " is thick, and hollowed into a groove, which is continuous below with the lacrimal groove on the nasal surface of the body : by the articulation of the medial margin of the groove with the anterior border of the lacrimal a corresponding groove on the lacrimal is brought into continuity, and together they form the lacrimal fossa for the lodgement of the lacrimal sac.
