The lacrimal bone (L., lacrima – tear) is a small facial bone that forms a portion of the anterior medial wall of the orbit.
Lacrimal Bone Anatomy on Lateral View:
Lacrimal fossa (or lacrimal sulcus; fossa for lacrimal sac) – depression along the junction of the lacrimal bone and maxilla bone that holds the lacrimal sac; tears formed by the sac drain through a duct into the nasal cavity.
Orbital plate (or orbital surface) – thin plate of bone that forms a portion of the medial wall of the orbit posterior to lacrimal fossa.
