| accessory lacrimal glands | Small, compound, branched, tubular glands located in the middle part of the lid (Wolfring's glands, 1872, or Ciaccio's glands, 1874) and along the superior and inferior fornices of the conjunctival sac (Krause's glands, 1854). These accessory glands are just scattered scraps of lacrimal gland tissue; all of them produce the same kind of tears and debouch on to the conjunctival surface. Henle's and Baumgarten's "glands" are in fact not glands at all, but mere epithelial invaginations. Synonym: glandulae lacrimales accessoriae. (05 Mar 2000) |

| ampulla of lacrimal canaliculus | A slight dilation at the angle of the lacrimal canaliculus immediately beyond the lacrimal punctum. Synonym: ampulla canaliculi lacrimalis. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
| anterior lacrimal crest | 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) |
| palpebral part of lacrimal gland | palpebral part of lacrimal gland |
| communicating branch of lacrimal nerve with zygomatic nerve | <anatomy, nerve> Nerve branch by which postsynaptic parasympathetic (secretomotor) fibres from the pterygopalatine ganglion are transferred from the zygomatic nerve to the lacrimal nerve (heretofore purely sensory) for distribution to the lacrimal gland. Synonym: ramus communicans nervi lacrimalis cum nervo zygomatico. (05 Mar 2000) |
| posterior lacrimal crest | 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) |
| hamular process of lacrimal bone | 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) |
| internal lacrimal fistula | A fistulous communication between the lacrimal sac and the ethmoidal sinus. Synonym: internal lacrimal fistula. (05 Mar 2000) |
| orbital part of lacrimal gland | See: lacrimal gland. (05 Mar 2000) |
| ethmoidal-lacrimal fistula | A fistulous communication between the lacrimal sac and the ethmoidal sinus. Synonym: internal lacrimal fistula. (05 Mar 2000) |
| excretory ducts of lacrimal gland | The multiple (6 to 10) excretory ducts of the lacrimal gland that open into the superior fornix of the conjunctival sac. Synonym: ductuli excretorii glandulae lacrimalis, excretory ductules of lacrimal gland. (05 Mar 2000) |
| excretory ductules of lacrimal gland | The multiple (6 to 10) excretory ducts of the lacrimal gland that open into the superior fornix of the conjunctival sac. Synonym: ductuli excretorii glandulae lacrimalis, excretory ductules of lacrimal gland. (05 Mar 2000) |
| lacrimal | Pertaining to the tears. (18 Nov 1997) |
| lacrimal apparatus | The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system. (12 Dec 1998) |
