| 설명 | 소리의 진동을 전기적 신호로 바꾸어 신경을 통해 대뇌에 전달하는 기관. 즉 소리를 느끼는 기관으로 달팽이 모양으로 생겼다. ◈소리를 느끼는 과정- 외부에서 들어온 소리는 이개에서 일단 모여 외이도를 통해서 고막으로 전달이 된다. 고막은 소리(소리란 공기의 진동에 의해서 생기는 것이다)에 따라 진동을 하게 된다. 이 진동은 귓속뼈이라는 3개의 작은 뼈를 진동시킨다. 3개의 귓바퀴는 각각 망치뼈, 모루뼈, 등자뼈로 망치뼈는 고막에 부착되어 있다. 등자뼈는 소리를 느끼는 달팽이 모양의 기관인 달팽이의 작은 구멍인 안뜰창에 연결이 된다. 즉 고막의 진동은 귓속뼈를 거쳐서 소리를 느끼는 기관인 달팽이에 전달이 된다. 달팽이는 속에 외림프(perilymph)와 내림프(endolymph)라는 액체로 차있고 이것은 안뜰창의 진동에 따라 움직이게 된다. 이 액체들의 움직임에 따라 역시 당팽이속의 기관인 코르티기관(organ of Corti)의 작은 털이있는 세포의 털을 진동시키고 털세포는 털의 움직임을 전기적 신호로 바꾸어 청신경을 통해서 뇌로 전달한다. |

| RVA | Right ventricular apex |
| base of cochlea | 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) |
|---|---|
| vestibular fissure of cochlea | A fine fissure in the lower part of the first turn of the cochlea, formed by a spiral lamina which projects from the outer wall of the cochlea but does not quite reach the osseous spiral lamina, thus leaving a narrow gap. (05 Mar 2000) |
| central canals of cochlea | Centrally placed channels that convey vessels and nerves to the apical turns of the cochlea. Synonym: canales longitudinales modioli, central canals of cochlea. (05 Mar 2000) |
| membranous cochlea | Spiral tube in the bony canal of the cochlea, lying on its outer wall between the scala vestibuli and scala tympani. (12 Dec 1998) |
| cochlea | The part of the internal ear that is concerned with hearing. It forms the anterior part of the labyrinth, is conical, and is placed almost horizontally anterior to the vestibule. (12 Dec 1998) |
| cupula of cochlea | The domelike apex of the cochlea. Synonym: cupula cochleae. (05 Mar 2000) |
| spiral canal of cochlea | 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) |
| spiral ganglion of cochlea | 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) |
| spiral ligament of cochlea | The thickened periosteal lining of the bony cochlea forming the outer wall of the cochlear duct to which the basal lamina attaches. Synonym: crista spiralis, ligamentum spirale cochleae, spiral crest. (05 Mar 2000) |
| stria vascularis of cochlea | The stratified epithelium lining the upper part of the ligamentum spirale cochleae; it is penetrated by capillaries and is believed to be the site of production of endolymph. Synonym: stria vascularis ductus cochlearis, psalterial cord, vascular stripe. (05 Mar 2000) |
| fenestra of the cochlea | An opening on the medial wall of the middle ear leading into the cochlea, closed in life by the secondary tympanic membrane. Synonym: cochlear window, fenestra of the cochlea, fenestra rotunda, round window. (05 Mar 2000) |
| apex | <dentistry> The very bottom of the root of your tooth. (08 Jan 1998) |
| apex auriculae | A point projecting upward and posteriorly from the free outcurved margin of the helix a little posterior to its upper end. Synonym: apex auriculae, apex satyri, Woolner's tip. (05 Mar 2000) |
| apex beat | The visible and/or palpable pulsation made by the apex of the left ventricle as it strikes the chest wall in systole; normally in the fifth intercostal space, about 10 cm to the left of the median line. (05 Mar 2000) |
| apex capitis fibulae | The pointed upper end of the fibular head to which is attached the arcuate popliteal ligament and part of the biceps femoris tendon. Synonym: apex capitis fibulae, styloid process of fibula. (05 Mar 2000) |
