| glandula lacrimalis | The gland that secretes tears; it consists of 6 to 12 separate compound tubuloalveolar serous glands, located in the upper lateral part of the orbit, and is partially divided into a smaller palpebral part and a larger orbital part by the aponeurosis of the levator palpebrae muscle. Synonym: glandula lacrimalis. (05 Mar 2000) |

| rivus lacrimalis | A space between the closed lids and the eyeball through which the tears flow to the punctum lacrimale. Synonym: Ferrein's canal. Origin: L. Rivus, stream, + Mediev. L. Lacrimalis, fr. L. Lacrima, a tear (05 Mar 2000) |
| plica lacrimalis | A fold of mucous membrane guarding the lower opening of the nasolacrimal duct. Synonym: plica lacrimalis, Bianchi's valve, Hasner's fold, Hasner's valve, Huschke's valve, Rosenmuller's valve. (05 Mar 2000) |
| crista lacrimalis anterior | A vertical ridge on the lateral surface of the frontal process of the maxilla that forms part of the medial rim of the orbit. Synonym: crista lacrimalis anterior. (05 Mar 2000) |
| crista lacrimalis posterior | A vertical ridge on the orbital surface of the lacrimal bone which, together with the anterior lacrimal crest, bounds the fossa for the lacrimal sac. Synonym: crista lacrimalis posterior. (05 Mar 2000) |
| hamulus lacrimalis | The hooklike lower end of the lacrimal crest, curving between the frontal process and orbital surface of the maxilla to form the upper aperture of the bony portion of the nasolacrimal canal. Synonym: hamulus lacrimalis, hamular process of lacrimal bone. (05 Mar 2000) |
| sacculus lacrimalis | The upper portion of the nasolacrimal duct into which empty the two lacrimal canaliculi; empty. Synonym: saccus lacrimalis, dacryocyst, sacculus lacrimalis, tear sac. (05 Mar 2000) |
| saccus lacrimalis | The upper portion of the nasolacrimal duct into which empty the two lacrimal canaliculi; empty. Synonym: saccus lacrimalis, dacryocyst, sacculus lacrimalis, tear sac. (05 Mar 2000) |

| nervus lacrimalis | <anatomy, nerve> A branch of the ophthalmic nerve supplying sensory fibres to the lateral part of the upper eyelid, conjunctiva, and lacrimal gland. The secretomotor fibres of the latter were conveyed to the lacrimal nerve by the communicating branch of the zygomatic nerve (a branch of the maxillary nerve). Synonym: nervus lacrimalis. (05 Mar 2000) |
| sulcus lacrimalis | The groove in the nasal surface of the maxilla which, together with the lacrimal bone, forms the fossa for the lacrimal sac. Synonym: sulcus lacrimalis. (05 Mar 2000) |
| incisura lacrimalis | The notch on the frontal process of the maxilla into which the lacrimal bone fits. Synonym: incisura lacrimalis. (05 Mar 2000) |
| lacus lacrimalis | The small cistern-like area of the conjunctiva at the medial angle of the eye, in which the tears collect after bathing the anterior surface of the eyeball and the conjunctival sac. Synonym: lacus lacrimalis, lacrimal bay. (05 Mar 2000) |
| fornix sacci lacrimalis | Fornix of the lacrimal sac; the upper, blind end of the lacrimal sac that extends above the openings of the lacrimal canaliculi. Synonym: fornix sacci lacrimalis. (05 Mar 2000) |
