| 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 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 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) |

| accessory process | A small apophysis at the posterior part of the base of the transverse process of each of the lumbar vertebrae. Synonym: processus accessorius, accessory tubercle. (05 Mar 2000) |
| acromial process | <anatomy> The lateral triangular projection of the spine of the scapula that forms the point of the shoulder and articulates with the clavicle. (27 Sep 1997) |
| activated sludge process | <procedure> A method of treating sewage and wastewater through microbial oxidation. Sewage previously treated in settling tanks is aerated to encourage the growth of nonpathogenic aerobic microorganisms (bacteria, yeasts, moulds and protozoans) which break the organic matter down into carbon dioxide, water and simple salts. After this activated sludge is produced, the wastewater undergoes further processing through anaerobic digestion, filtering and chlorination. (29 Dec 1997) |
