|---|---|---|---|
| 설명 | 감각세포가 받은 자극을 중추신경에 전달하는 신경. 눈이나 피부 등에 있는 감각기가 외부로부터 자극을 받으면 감각신경을 거쳐 척수와 대뇌겉질까지 감각이 전달된다. 이와 같이 외부로부터 내부를 향해 전달되는 감각신경은 구심성 신경계통이며, 원심성 운동신경계통 및 자율신경계통에 필적하는 말초신경의 하나이다. 이 감각신경에는 후각신경(뇌신경Ⅰ)-시각신경(뇌신경Ⅱ)-눈돌림신경(뇌신경Ⅲ)-삼차신경(뇌신경Ⅴ)-얼굴신경(뇌신경Ⅶ)-청각신경(뇌신경Ⅷ)-혀인두신경(뇌신경Ⅸ)-미주신경(뇌신경Ⅹ) 및 척수신경이 있다. 감각신경 중 미주신경을 제외하면 모두 두부에 분포되어 있고, 후각신경-시각신경-청각신경의 세가지는 특히 분화된 감각상피를 지배한다. 혀인두신경은 미각의 말단장치와 그 밖의 부분에 연결되고 미주신경은 흉강과 복강의 기관에 분포되어 구심성 충격을 중추에 전달하며 삼차신경은 척수의 각 마디에 있는 신경에 해당하여(머리의 피부-점막 등의 표면감각과 심부감각을 관장한다. 척수의 감각신경계통에도 피부와 심부, 내장의 분포에 따른 구별이 있다. |

| principal sensory nucleus of the trigeminus | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |

| principal sensory nucleus of trigeminal nerve | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |
| ganglia, sensory | Clusters of neurons in the somatic peripheral nervous system which contain the cell bodies of sensory nerve axons. Sensory ganglia may also have intrinsic interneurons and non-neuronal supporting cells. (12 Dec 1998) |
| receptors, sensory | Specialised neurons or parts of neurons which transduce sensory information and relay it centrally. Included are receptors for stimuli outside the body (exteroceptors) as well as receptors for stimuli from within the body itself (interoceptors and proprioceptors). Sensory receptors may include accessory structures which condition (e.g., filter) the input received by the receptor neurons themselves. (12 Dec 1998) |
| hereditary sensory radicular neuropathy | Neuropathy characterised by the occurrence of severe, relapsing foot ulcerations of neuropathic origin, destruction of terminal digits of feet and hands, and a loss of sensation; autosomal dominant inheritance is associated with onset in the second decade or later. (05 Mar 2000) |
| secondary sensory cortex | A cortical region occupying the parietal operculum (upper lip of the lateral sulcus) closely posterior to the foot of the postcentral gyrus; like the primary somatic-sensory cortex of the postcentral gyrus, this region receives sensory impulses originating in face, trunk, and limbs; projections to the s.s.c. Are from the ventral basal complex (ventral posteromedial and posterolateral thalamic nuclei) and from the primary somesthetic cortex. (05 Mar 2000) |
| secondary sensory nuclei | Nuclei terminales, collective term indicating those nerve cell groups in the rhombencephalon and spinal cord in which the afferent fibres of the spinal and cranial nerves terminate. Synonym: nuclei terminationis, secondary sensory nuclei. (05 Mar 2000) |
| sensory | <otolaryngology> Pertaining to or subserving sensation. Origin: L. Sensorius (18 Nov 1997) |
| sensory amblyopia | A suppression of central vision in one eye due to faulty image formation; for example, by a corneal scar, a cataract, or a droopy eyelid. Synonym: deprivation amblyopia. (05 Mar 2000) |
| sensory amusia | Inability to interpret or appreciate musical sounds. (05 Mar 2000) |
| sensory aphasia | Aphasia in which there is impairment in the comprehension of spoken and written words, associated with effortless, articulated, but paraphrasic, speech and writing; malformed words, substitute words, and enologisms are charcteristic. When severe, and speech is incomprehensible, it is called jargon aphasia. The patient often appears unaware of his deficit. Synonym: fluent aphasia, impressive aphasia, posterior aphasia, psychosensory aphasia, receptive aphasia, Wernicke's aphasia. (05 Mar 2000) |
| sensory areas | The outer portion of the brain, consisting of layersof nerve cells and the pathways that connect them. The cerebralcortex is the part of the brain in which thought processes take place.In Alzheimer's disease, nerve cells in the cerebral cortex die. (22 May 1997) |
| sensory ataxia | An ataxia due to impairment of position sense caused by lesions located at some point along the central or peripheral sensory pathways. (05 Mar 2000) |
| sensory cell | A cell in the peripheral nervous system that receives afferent (sensory) input; sensory receptor cells. (05 Mar 2000) |
| sensory cortex | Formerly denoting specifically the somatic sensory cortex, but now used to refer collectively to the somatic sensory, auditory, visual, and olfactory regions of the cerebral cortex. (05 Mar 2000) |
| sensory nucleus |
The nucleus of termination of the afferent fibers of a peripheral nerve.
