The apposition of the Lacrimal Bone (the smallest bone in your
body) and the Maxilla (your upper jaw). This is considered to be a
Harmonic suture, as each bone meets without overlapping. Also known
as sutura lacrimomaxillaris, the Lacrimomaxillary suture occurs medially along the wall of the orbit (eye socket).
