| inferior nasal arteriole of retina | The branch of the central artery of the retina that supplies the lower medial, or nasal, part of the retina. Synonym: arteriola nasalis retinae inferior. (05 Mar 2000) |
|---|---|
| inferior nasal colliculus | The ovoid, paired, inferior eminence of the laminae of mesencephalic tectum; it receives the lateral lemniscus and projects by way of the brachium of inferior colliculus to the medial geniculate body of the thalamus, and is thus an essential way-station in the central auditory pathway. Synonym: colliculus inferior, corpus quadrigeminum posterius, inferior nasal colliculus, posterior quadrigeminal body. (05 Mar 2000) |
| inferior nasal concha | A thin, spongy, bony plate with curved margins, on the lateral wall of the nasal cavity, separating the middle from the inferior meatus; it articulates with the ethmoid, lacrimal, maxilla, and palate bones, the above bony plate and its thick mucoperiosteum containing an extensive cavernous vascular bed for heat exchange. Synonym: concha nasalis inferior, inferior turbinated bone, turbinated body. (05 Mar 2000) |
| inferior nasal venule of retina | The small vein that passes from the inferior medial (nasal) part of the retina to join the central vein. Synonym: venula nasalis retinae inferior. (05 Mar 2000) |
| internal nasal branches | Branches to nasal cavity. Internal nasal branches of 1) infraorbital nerve (rami nasales interni nervi infraorbitalis ); 2) nasociliary nerve (rami nasales interni nervi ethmoidalis anterioris ). Synonym: rami nasales interni. (05 Mar 2000) |
| olfactory sulcus of nasal cavity | The narrow groove in the nasal cavity above the agger nasi that leads from the atrium to the olfactory area. Synonym: sulcus olfactorius cavum nasi. (05 Mar 2000) |
| transverse nasal groove | A single deep horizontal groove at the level of the alae, with no associated defects. Synonym: transverse nasal groove. (05 Mar 2000) |
| external nasal branches | Branches to external aspect of nose. The external nasal branches of 1) infraorbital nerve, rami nasales externii nervi infraorbitalis, 2) nasociliary nerve, rami nasales externi nervi ethmoidalis anterioris. Synonym: rami nasales externi. (05 Mar 2000) |
| external nasal veins | Several vessels that drain the external nose, emptying into the angular or facial vein. Synonym: venae nasales externae. (05 Mar 2000) |
| lateral nasal artery | <anatomy, artery> A branch of the facial artery which supplies the dorsum and ala of the nose. (05 Mar 2000) |
| lateral nasal branches of anterior ethmoidal nerve | <anatomy, nerve> Branches of nasociliary nerve distributed to walls of nasal cavity. Synonym: rami nasales laterales nervi ethmoidalis anterioris. (05 Mar 2000) |
| lateral nasal fold | An ectodermally covered mesenchymal swelling separating the embryonic olfactory pit from the developing eye. Synonym: lateral nasal fold, lateral nasal primordium, lateral nasal process. (05 Mar 2000) |
| lateral nasal primordium | An ectodermally covered mesenchymal swelling separating the embryonic olfactory pit from the developing eye. Synonym: lateral nasal fold, lateral nasal primordium, lateral nasal process. (05 Mar 2000) |
| lateral nasal process | An ectodermally covered mesenchymal swelling separating the embryonic olfactory pit from the developing eye. Synonym: lateral nasal fold, lateral nasal primordium, lateral nasal process. (05 Mar 2000) |
| lateral nasal prominence | An ectodermally covered mesenchymal swelling separating the embryonic olfactory pit from the developing eye. Synonym: lateral nasal fold, lateral nasal primordium, lateral nasal process. (05 Mar 2000) |
