| canalis nervi facialis | 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) |

| radix nervi facialis | <anatomy, nerve> Fibres running from the facial motor nucleus upward to the facial colliculus where they curve around the abducens nucleus and then pass peripherally between the superior olive and sensory nucleus of the trigeminal, to emerge as the facial nerve from the pontomedullary groove. Synonym: radix nervi facialis. (05 Mar 2000) |
| rami buccales nervi facialis | <anatomy, nerve> Motor branches of the facial nerve distributed to buccina or muscle and other muscles of facial expression below orbit and above chin. Synonym: rami buccales nervi facialis. (05 Mar 2000) |
| rami temporales nervi facialis | <anatomy, nerve> <anatomy, neurology> Branches of facial nerve innervating the superior portion of the orbicularis oculi muscle and other muscles of facial expression above the eye. Synonym: rami temporales nervi facialis. (05 Mar 2000) |
| rami zygomatici nervi facialis | Branches of facial nerve crossing upper cheek to supply orbicularis oculi muscle. Synonym: rami zygomatici nervi facialis. (05 Mar 2000) |
| geniculum nervi facialis | <anatomy, nerve> A rectangular bend of the facial nerve in the facial canal where it turns posterior in the medial wall of the middle ear (external geniculum), complex loop of facial nerve fibres around the abducens nucleus (internal geniculum). Synonym: geniculum nervi facialis. (05 Mar 2000) |
| genu nervi facialis | <anatomy, nerve> The curve which the fibres of the root of the facial nerve describe around the abducens nucleus in the pontine tegmentum; the internal genu of the facial nerve. Synonym: genu nervi facialis. (05 Mar 2000) |
| nucleus nervi facialis | A group of motor neurons located in the ventrolateral region of the lower pontine tegmentum and innervating the facial muscles, the stapedius muscle in the middle ear, the posterior limb of the musculus digastricus, and the stylohyoid muscle. Synonym: nucleus nervi facialis, facial motor nucleus, motor nucleus of facial nerve, nucleus facialis. (05 Mar 2000) |
| ramus tonsillaris arteriae facialis | <anatomy, artery> Primary blood supply to palatine tonsil, with extensive anastomoses with other tonsillar arteries. Synonym: ramus tonsillaris arteriae facialis. (05 Mar 2000) |
| arteria lingualis | <anatomy, artery> Origin, external carotid; distribution, runs along under surface of tongue, terminates as deep lingual artery; branches, suprahyoid and dorsal lingual branches and sublingual artery. Synonym: arteria lingualis. (05 Mar 2000) |
| rami dorsales linguae arteriae lingualis | <anatomy, artery> Branches of the lingual artery to the posterior third or root of tongue. Synonym: rami dorsales linguae arteriae lingualis. (05 Mar 2000) |
| papilla lingualis | 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) |
| vena lingualis | <anatomy, vein> Receives blood from the tongue, sublingual and submandibular glands, and muscles of the floor of the mouth; empties into the internal jugular or the facial vein. Synonym: vena lingualis. (05 Mar 2000) |
| glandula lingualis anterior | One of the small mixed glands deeply placed near the apex of the tongue on each side of the frenulum. Synonym: glandula lingualis anterior, apical gland, Bauhin's gland, Blandin's gland, Nuhn's gland. (05 Mar 2000) |
| gyrus lingualis | A relatively short horizontal convolution on the inferomedial aspect of the occipital and temporal lobes, demarcated from the lateral occipitotemporal or fusiform gyrus by the deep collateral sulcus, from the cuneus by the calcarine sulcus; its anterior extreme abuts the isthmus of the parahippocampal gyrus; the medial or upper strip of the gyrus forming the lower bank of the calcarine sulcus corresponds to the inferior half of the striate area or primary visual cortex and represents the contralateral upper quadrant of the binocular field of vision. Synonym: gyrus lingualis, gyrus occipitotemporalis medialis, medial occipitotemporal gyrus. (05 Mar 2000) |
