Lacrimal bone

This video tutorial discusses the lacrimal bone, the smallest bone in the skull, located on the orbital plate of the ethmoid bone. It highlights the bone's position in the bony orbit and its Latin origin, 'lacryma,' meaning tears. The tutorial explains the differences between the lateral and medial surfaces of the lacrimal bone, including the lacrimal groove and its role in forming the fossa for the lacrimal sac. It also covers the bone's articulations with the frontal process of the maxilla, frontal bone, and ethmoid cells. The video concludes with a call to explore more anatomy resources on Kenhub.
