| ear canal, self-cleaning | most of the time the ear canals are self-cleaning, that is, there is a slow and orderly migration of ear canal skin from the eardrum to the outer opening. Old earwax is constantly being transported from the deeper areas of the ear canal to the opening where it usually dries, flakes, and falls out. (12 Dec 1998) |

| Jacobson's canal | A minute canal passing from the inferior surface of the petrous portion of the temporal bone between the jugular fossa and carotid canal to the floor of the tympanic cavity.

| facial canal | The bony passage in the temporal bone through which the facial nerve passes; the facial canal commences at the internal auditory meatus with the horizontal part which passes at first anteriorly (medial crus of facial canal) then turns posteriorly at the geniculum of the facial canal to pass medial to the tympanic cavity (lateral crus of facial canal); finally, it turns downward (descending part of facial canal) to reach the stylomastoid foramen. Synonym: canalis nervi facialis, aqueductus fallopii, fallopian aqueduct, fallopian canal. (05 Mar 2000) |

| Fontana's canal | sinus venosus sclerae |
| lateral canal | A channel leading from the root pulp laterally through the dentin to the periodontal tissue; may be found anywhere in the tooth root, but is more common in the apical third of the root. Synonym: lateral canal. (05 Mar 2000) |
| lateral crus of facial canal | Laterally-placed, posteriorly-directed second portion of the horizontal part of the facial canal. See: horizontal part of facial canal. Synonym: lateral crus of horizontal part of the facial canal. (05 Mar 2000) |
