| area nervi facialis | <anatomy, nerve> The area in the fundus of the internal acoustic meatus superior to the transverse crest through which the facial nerve passes to enter the facial canal. Synonym: area nervi facialis. (05 Mar 2000) |
|---|---|
| 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) |
| ramus cervicalis nervi facialis | An alternate term for cervical branch of facial nerve. Ramus chiasmaticus, the chiasmatic branch, a branch of the middle cerebral artery to the optic chiasm. (05 Mar 2000) |
| ramus colli nervi facialis | <anatomy, nerve> The most inferior branch of the parotid plexus of the facial nerve, it descends to innervate the platysma muscle. Synonym: ramus colli nervi facialis, ramus cervicalis nervi facialis. (05 Mar 2000) |
| ramus communicans nervi facialis cum plexu tympanico | A fine branch of facial nerve joining the tympanic branch of the glossopharyngeal nerve. Synonym: ramus communicans nervi facialis cum plexu tympanico. (05 Mar 2000) |
| ramus digastricus nervi facialis | <anatomy, nerve> Branch of the facial nerve innervating the posterior belly of the digastric muscle. Synonym: ramus digastricus nervi facialis. (05 Mar 2000) |
| ramus lingularis nervi facialis | Lingual branch (inconstant) of the stylohyoid branch of the facial nerve. Synonym: ramus lingularis nervi facialis. (05 Mar 2000) |
| ramus marginalis mandibulae nervi facialis | <anatomy, nerve> Branch of facial nerve which parallels the mandibular margin innervating risorius muscle and muscles of lower lip and chin. Synonym: ramus marginalis mandibulae nervi facialis. (05 Mar 2000) |
| ramus stylohyoideus nervi facialis | <anatomy, nerve> Branch of facial nerve to stylohyoid muscle. Synonym: ramus stylohyoideus 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) |
| 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) |
