| apertura externa canaliculi cochleae | The external opening of the cochlear aqueduct on the temporal bone medial to the jugular fossa. Synonym: apertura externa canaliculi cochleae. (05 Mar 2000) |
|---|---|
| aqueductus cochleae | A fine canal connecting the perilymphatic space of the cochlea with the subarachnoid space. Synonym: ductus perilymphaticus, aqueductus cochleae, cochlear aqueduct. (05 Mar 2000) |
| area cochleae | The area inferior to the transverse crest of the fundus of the internal acoustic meatus through which the filaments of the cochlear nerve pass to enter the cochlea; forms the base of the cone-shaped modiolus about which the cochlear canal spirals. See: base of modiolus. Synonym: area cochleae. (05 Mar 2000) |
| basis cochleae | The enlarged part of the cochlea that is directed posteriorly and medially and lies close to the internal acoustic meatus. Synonym: basis cochleae. (05 Mar 2000) |
| canaliculus cochleae | A minute canal in the temporal bone that passes from the cochlea inferiorly to open in front of the medial side of the jugular fossa. It contains the perilymphatic duct. Synonym: canaliculus cochleae. (05 Mar 2000) |
| canalis spiralis cochleae | The winding tube of the bony labyrinth which makes two and a half turns about the modiolus of the cochlea; it is divided incompletely into two compartments by a winding shelf of bone, the bony spiral lamina. Synonym: canalis spiralis cochleae, Rosenthal's canal, spiral canal of cochlea. (05 Mar 2000) |
| ganglion spirale cochleae | An elongated ganglion of bipolar sensory nerve cell bodies on the cochlear part of the vestibulocochlear nerve in the spiral canal of the modiolus; each ganglion cell gives rise to a peripheral process that passes between the layers of the bony spiral lamina to the organ of Corti, and a central axon that enters the hindbrain as a component of the inferior (cochlear) root of the eighth nerve. Synonym: ganglion spirale cochleae, auditory ganglion, cochlear ganglion, Corti's ganglion, spiral cochlear ganglion. (05 Mar 2000) |
| vena aqueductus cochleae | It drains the cochlea, sacculus, and part of the utricules, and empties into the superior bulb of the jugular vein by accompanying the perilymphatic duct through the cochlear canaliculus. Synonym: vena aqueductus cochleae, vein of cochlear aqueduct, vena canaliculi cochleae. (05 Mar 2000) |
| vena canaliculi cochleae | It drains the cochlea, sacculus, and part of the utricules, and empties into the superior bulb of the jugular vein by accompanying the perilymphatic duct through the cochlear canaliculus. Synonym: vena aqueductus cochleae, vein of cochlear aqueduct, vena canaliculi cochleae. (05 Mar 2000) |
| columella cochleae | modiolus labii |
| crest of fenestrae cochleae | The edge of the opening of the cochlear window to which the secondary tympanic membrane is attached. Synonym: crista fenestrae cochleae, crest of cochlear opening. (05 Mar 2000) |
| crista fenestrae cochleae | The edge of the opening of the cochlear window to which the secondary tympanic membrane is attached. Synonym: crista fenestrae cochleae, crest of cochlear opening. (05 Mar 2000) |
| cupula cochleae | The domelike apex of the cochlea. Synonym: cupula cochleae. (05 Mar 2000) |
| hamulus cochleae | The upper hooklike termination of the bony spiral lamina at the apex of the cochlea. Synonym: hamulus laminae spiralis, hamulus cochleae, hook of spiral lamina. (05 Mar 2000) |
| tuber cochleae | 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) |
