|---|---|
| musculus tensor tympani | <anatomy, muscle> Origin, the cartilaginous part of the auditory (eustachian) tube and the walls of its hemi-canal just above the bony portion of the auditory tube; insertion, handle of malleus; action, draws the handle of the malleus medialward tensing the tympanic membrane to protect it from excessive vibration by loud sounds. Nerve supply, branches of trigeminal through the otic ganglion. Synonym: musculus tensor tympani, tensor muscle of tympanic membrane, Toynbee's muscle. (05 Mar 2000) |
| posterior canaliculus of chorda tympani | A canal leading from the facial canal to the tympanic cavity through which the chorda tympani nerve enters this cavity. Synonym: canaliculus chordae tympani, iter chordae posterius, small canal of chorda tympani. (05 Mar 2000) |
| saemicanal for tensor tympani muscle | <anatomy> Saemicanal of the tensor muscle of the tympanum; the superior division of the canalis musculotubarius containing the tensor tympani muscle. Synonym: saemicanalis musculi tensoris tympani. (05 Mar 2000) |
| saemicanalis musculi tensoris tympani | <anatomy> Saemicanal of the tensor muscle of the tympanum; the superior division of the canalis musculotubarius containing the tensor tympani muscle. Synonym: saemicanalis musculi tensoris tympani. (05 Mar 2000) |
| promontorium cavi tympani | A rounded eminence on the labyrinthine wall of the middle ear, caused by the first coil of the cochlea. Synonym: promontorium cavi tympani, tuber cochleae, tympanic promontory. (05 Mar 2000) |
| scala tympani | The lower tube of the cochlea, extending from the round window to the helicotrema and containing perilymph. (12 Dec 1998) |
| pyramis tympani | A conical projection posterior to the vestibular window in the middle ear; it is hollow and contains the stapedius muscle. Synonym: pyramid of tympanum, pyramidal eminence, pyramis tympani. (05 Mar 2000) |
| sinus tympani | A depression in the tympanic cavity posterior to the tympanic promontory. Synonym: sinus tympani. Sinus unguis, the deep cleft housing the root of the nail. Synonym: sinus of nail. (05 Mar 2000) |
| small canal of chorda tympani | A canal leading from the facial canal to the tympanic cavity through which the chorda tympani nerve enters this cavity. Synonym: canaliculus chordae tympani, iter chordae posterius, small canal of chorda tympani. (05 Mar 2000) |
| nerve of tensor tympani muscle | <anatomy> A branch of the mandibular nerve conveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor tympani muscle. Synonym: nervus tensoris tympani. (05 Mar 2000) |
| nervus tensoris tympani | <anatomy> A branch of the mandibular nerve conveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor tympani muscle. Synonym: nervus tensoris tympani. (05 Mar 2000) |
| tegmen tympani | The roof of the middle ear, formed by the thinned anterior surface of the petrous portion of the temporal bone. Its anterior edge is inserted into the petrosquamous fissure so that it can be seen as a wedge of bone subdividing that fissure into a squamo tympanic and a petrotympanic fissure. Synonym: roof of tympanum. (05 Mar 2000) |
| tensor tympani | <anatomy, muscle> Origin, the cartilaginous part of the auditory (eustachian) tube and the walls of its hemi-canal just above the bony portion of the auditory tube; insertion, handle of malleus; action, draws the handle of the malleus medialward tensing the tympanic membrane to protect it from excessive vibration by loud sounds.
