| 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. |

| annulospiral ending | One of two types of sensory nerve ending associated with a neuromuscular spindle (the other being the flower-spray ending); after entering the muscle spindle, the fibre divides into two flat ribbon-like branches that wind themselves in rings or spirals about the intrafusal muscle fibres. Synonym: annulospiral organ. (05 Mar 2000) |

| calyciform ending | A synaptic ending in relation to certain neuroepithelial hair cells of the inner ear. (05 Mar 2000) |
| hederiform ending | A type of free sensory ending in the skin. (05 Mar 2000) |
| sole-plate ending | The specialised postsynaptic region of a muscle cell. The motor endplate is immediately across the synaptic cleft from the presynaptic axon terminal. Among its anatomical specializations are junctional folds which harbor a high density of cholinergic receptors. See: neuromuscular junction (12 Dec 1998) |
| nerve ending | <physiology> A connection between excitable cells, by which an excitation is conveyed from one to the other. 1. Chemical synapse: one in which an action potential causes the exocytosis of neurotransmitter from the presynaptic cell, which diffuses across the synaptic cleft and binds to ligand gated ion channels on the post synaptic cell. These ion channels then affect the resting potential of the post synaptic cell. 2. Electrical synapse: one in which electrical connection is made directly through the cytoplasm, via gap junctions. 3. Rectifying synapse: one in which action potentials can only pass across the synapse in one direction (all chemical and some electrical synapses). 4. Excitatory synapse: one in which the firing of the presynaptic cell increases the probability of firing of the postsynaptic cell. 5. Inhibitory synapse: one in which the firing of the presynaptic cell reduces the probability of firing of the postsynaptic cell. (10 Jan 1998) |
| ending | 1. A termination or conclusion. 2. A nerve ending. (05 Mar 2000) |
| epilemmal ending | A nerve ending in close relation to the outer surface of the sarcolemma. (05 Mar 2000) |
| flower-spray ending | One of the two types of sensory nerve ending associated with the neuromuscular spindle (the other being the annulospiral ending); in this type, the fibre branches spread out upon the surface of the intrafusal fibres like a spray of flowers. Synonym: flower-spray organ of Ruffini. (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) |
| 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) |
| 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 ending |
A termination of an afferent nerve fiber that upon stimulation gives rise to a sensation. SEE: receptor, sensory.
