From Wikipedia, the free encyclopedia

Lacrimal hamulus
Latin	hamulus lacrimalis
Gray's	subject #39 164
Dorlands/Elsevier	h_02/12407626

The posterior lacrimal crest, with a part of the orbital surface immediately behind it, gives origin to the lacrimal part of the Orbicularis oculi and ends below in a small, hook-like projection, the lacrimal hamulus, which articulates with the lacrimal tubercle of the maxilla, and completes the upper orifice of the lacrimal canal; it sometimes exists as a separate piece, and is then called the lesser lacrimal bone.
