| incisive papilla | A slight elevation of the mucosa at the anterior extremity of the raphe of the palate. Synonym: papilla incisiva, palatine papilla. Interdental papilla, the gingiva that fills the interproximal space between two adjacent teeth. Synonym: gingival septum, interproximal papilla. (05 Mar 2000) |

| interproximal papilla | interdental papilla |
| optic papilla | The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve. Because the retina at the optic disk has no photoreceptors there is a corresponding blind spot in the visual field. (12 Dec 1998) |
| urethral papilla | Papilla urethralis, the slight projection often present in the vestibule of the vagina marking the urethral orifice. (05 Mar 2000) |
| lingual papilla | One of numerous variously shaped projections of the mucous membrane of the dorsum of the tongue. Synonym: papilla lingualis. The lingual portion of the gingiva filling the interproximal space between adjacent teeth; in molar and premolar areas, there may be separate lingual and buccal interdental papillae. See: interdental papilla. (05 Mar 2000) |
| 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) |
