|---|---|---|---|
| 설명 | 청신경(제8뇌신경)의 신경겉을 싸고 있는 집(sheath)의 슈반세포(Schwann cell)에서 기원하는 종양-뇌종양 중 비교적 흔하며 대개 40~50대에 호발한다. 증상으로는 귀울림, 난청, 소뇌기능장애 등이 있으며, 이중 귀울림이 가장 초기의 증상이다. |

| 영문 | patellar reflex | 한글 | 무릎반사 |
|---|---|---|---|
| 설명 | 무릎부위에서 넙다리네갈래근의 힘줄을 망치로 두들기면 넙다리네갈래근이 수축하여 아랫다리가 앞으로 뻗는 반사. 피라밋로의 장애에서는 항진하고, 척수전각이나 말초신경의 장애 및 근육병에서는 감약된다. |

| 영문 | light reflex | 한글 | 빛반사 |
|---|---|---|---|
| 설명 | 1. 한쪽 눈에 빛을 비추면, 이 빛은 시각신경에 의해 뇌에 전달되고, 이 자극은 사람의 의지와 무관하게 곧, 눈돌림신경으로 전달되어 양쪽 눈의 동공이 축소하게 된다. 이런 모든 일련의 과정을 빛반사라 부르는데 이것은 사람이 어두운 곳에 가거나 어두운 곳에서 갑자기 밝은 곳에 나갔을 때, 동공이 반사적으로 움직이는 것과 같은 것이다. 2. 고막에서 반사하는 광상. 3. 망막경의 거울로 망막에서 반사하는 고리모양의 많은 점. |

| reflex, acoustic | Intra-aural contraction of tensor tympani and stapedius in response to sound. (12 Dec 1998) |
|---|---|
| acoustic | Pertaining to the sense of hearing, the organs of hearing, or the science of sounds; auditory. Acoustic duct, the auditory duct, or external passage of the ear. Acoustic telegraph, a telegraph making audible signals; a telephone. Acoustic vessels, brazen tubes or vessels, shaped like a bell, used in ancient theaters to propel the voices of the actors, so as to render them audible to a great distance. Origin: F. Acoustique, Gr. Relating to hearing, fr. To hear. A medicine or agent to assist hearing. Source: Websters Dictionary (01 Mar 1998) |
| acoustic agraphia | The inability to write from dictation. (05 Mar 2000) |
| acoustic aphasia | An impairment in comprehension of the auditory forms of language and communication, including the ability to write from dictation in the presence of normal hearing. Spontaneous speech, reading, and writing are not affected. Synonym: acoustic aphasia, word deafness. (05 Mar 2000) |
| acoustic area | The floor of the lateral recess of the fourth ventricle, extending medially to the limiting sulcus and overlying the cochlear and vestibular nuclei of the rhombencephalon. Synonym: area acustica. (05 Mar 2000) |
| acoustic cell | A hair cell of the organ of Corti. (05 Mar 2000) |
| acoustic crest | An elevation on the inner surface of the ampulla of each saemicircular duct; filaments of the vestibular nerve pass through the crista to reach hair cells on its surface; the hair cells are capped by the cupula, a gelatinous protein-polysaccharide mass. Synonym: crista ampullaris, acoustic crest, transverse septum. (05 Mar 2000) |
| acoustic enhancement | A manifestation of increased acoustic signal amplitude returning from regions beyond an object which causes little or no attenuation of the sound beam. Compare: acoustic shadow. (05 Mar 2000) |
| acoustic impedance | The resistance that a material offers to the passage of a sound wave (colloquial); a property of a medium computed as the product of density and sound propagation speed (characteristic acoustic impedance). Discontinuities in acoustic impedance are responsible for the echoes on which ultrasound imaging is based. Unit: the rayl. (05 Mar 2000) |
| acoustic impedance tests | Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance). (12 Dec 1998) |
| acoustic lemniscus | A bundle of ascending fibres that originate from the cochlear and auditory relay nuclei of the rhombencephalon, enter the trapezoid body, a transverse fibre stratum in which about half their number decussate, and from here turn rostrally along the lateral side of the spinothalamic tract; in the midbrain, it arches dorsally and enters the inferior colliculus in which all of its fibres terminate; the auditory pathway is transsynaptically extended from here by the brachium of the inferior colliculus to the medial geniculate body of the thalamus, from which in turn the auditory radiation leads to the auditory cortex; intercalated in the trapezoid body and along the ascending trajectory of the lemniscus are several cell groups in which part of the fibres synapse. Synonym: lemniscus lateralis, acoustic lemniscus, auditory lemniscus, auditory tract, lateral fillet. (05 Mar 2000) |
| acoustic lens | In ultrasonography, a lens used to focus or diverge a sound beam; may be simulated by electronic manipulation of signals. (05 Mar 2000) |
| acoustic maculae | Thickened areas of the saccule and utricle where the termination of the vestibular nerve occurs. (12 Dec 1998) |
| acoustic meatus | The passage leading inward through the tympanic portion of the temporal bone, from the auricle to the tympanic membrane; it consists of a bony (inner) portion and a fibrocartilaginous (outer) portion, the cartilaginous external acoustic meatus. Synonym: meatus acusticus externus, acoustic meatus, antrum auris, auditory canal, external auditory meatus. (05 Mar 2000) |
| acoustic nerve | <anatomy, nerve> The 8th cranial nerve. The acoustic (or vestibulocochlear) nerve has a cochlear part which is concerned with hearing and a vestibular part which mediates the sense of balance and head position. The fibres of the cochlear nerve originate from neurons of the spiral ganglion and project to the cochlear nuclei. The fibres of the vestibular nerve arise from neurons of scarpa's ganglion and project to the vestibular nuclei. (12 Dec 1998) |
| acoustic reflex t. |
measurement of the acoustic reflex threshold by testing for contraction of the stapedial muscle in response to sound; used to differentiate between conductive and sensorineural deafness and to diagnose acoustic neuroma.

| acoustic reflex threshold |
The decibel level that provokes reflex contraction of the stapedius muscle. Tests that measure the triggering of the acoustic stapedius reflex are used to determine the presence of sensorineural hearing loss.
