    • n lacrymal One of the bones of the face in vertebrates; in man, the os unguis, or nail-bone, so called from its resemblance in size and shape to a human finger-nail. It is situated wholly within the orbit of the eye, on the inner side, in relation with the lacrymal or nasal duct, whence the name. In vertebrates other than man it is usually a much larger and stouter bone, situated externally upon the face, commonly forming a part of the bony brim of the orbit. It is essentially a membrane bone, forming one of a series which in some animals constitutes an outer arcade along the side of the skull, over the orbit, approximately parallel with the zygomatic arch. Also called lacrymale, os lacrymale, os unguis, and os tarsale. See cut under skull.
