| 설명 | 생물이 자신의 몸과 주위에서 일어나는 각종 변화를 감지하고 종합하여 적절한 반응을 일으키도록 하는 기관. 수많은 신경 세포로 되어 있다. 육안상 끈 모양의 구조로서, 중추신경계와 신체의 각 부분 사이에서 신경충동을 전달하는 신경섬유의 집합이다. 신경은 신경섬유의 다발을 둘러싸는 결합조직성의 집(sheath)으로 이루어진다. 각 신경섬유속은 신경다발막(perineurium)이라 부르는 결합조직성의 고유의 집으로 둘러싸여 있으며, 막의 내면은 편평한 중피세포의 막으로 되어 있다. 매우 작은 신경은 모신경에서 나온 단 한개의 신경삭으로 이루어지기도 한다. 이러한 신경속내에서, 현미경으로 관찰될 수 있는 각 신경섬유는 간질성 결합조직인 신경섬유막(endoneurium)으로 둘러싸여 있다. 각 신경섬유(축삭과 이를 싸고 있는 집)는 원형질로 된 기질인 축삭형질(axoplasm)과 이것내의 유형성분으로 구성되어 있고, 전체구조는 얇은 축삭집(axolemma)으로 둘러싸여 있으며, 신경집세포에 유래한 지질층인 말이집(myelin sheath)이 있는 것도 있고, 없는 것도 있다.  |

|---|---|
| nerve | 1. <anatomy> One of the whitish and elastic bundles of fibres, with the accompanying tissues, which transmit nervous impulses between nerve centers and various parts of the animal body. An ordinary nerve is made up of several bundles of nerve fibres, each bundle inclosed in a special sheath (the perineurium) and all bound together in a connective tissue sheath and framework (the epineurium) containing blood vessels and lymphatics. 2. A sinew or a tendon. 3. Physical force or steadiness; muscular power and control; constitutional vigor. "he led me on to mightiest deeds, Above the nerve of mortal arm." (Milton) 4. Steadiness and firmness of mind; self-command in personal danger, or under suffering; unshaken courage and endurance; coolness; pluck; resolution. 5. Audacity; assurance. 6. <botany> One of the principal fibrovascular bundles or ribs of a leaf, especially when these extend straight from the base or the midrib of the leaf. 7. <zoology> One of the nervures, or veins, in the wings of insects. <anatomy> Nerve cell, the operation of stretching a nerve in order to remedy diseases such as tetanus, which are supposed to be influenced by the condition of the nerve or its connections. Origin: OE. Nerfe, F. Nerf, L. Nervus, akin to Gr. Sinew, nerve; cf. String, bowstring; perh. Akin to E. Needle. Cf. Neuralgia. Source: Websters Dictionary (01 Mar 1998) |
| nerve avulsion | The tearing away of a peripheral nerve at its point of origin from its parent nerve due to traction. (05 Mar 2000) |
| nerve biopsy | <investigation, procedure, surgery> A procedure which involves the removal of a small specimen of nerve tissue for microscopic analysis. The ankle or wrist are the most common sites used for nerve biopsy. Conditions such as amyloidosis, sarcoidosis, metabolic polyneuropathy, leprosy, demyelination, alcoholic neuropathy, Charcot-Marie-tooth disease, peroneal nerve dysfunction, mononeuritis multiplex and other polyneuropathies may be detected using this study. (21 Mar 1998) |
| nerve block | Interruption of the conduction of impulses in peripheral nerves or nerve trunks by the injection of a local anaesthetic solution. (12 Dec 1998) |
| nerve block anaesthesia | Conduction anaesthesia in which local anaesthetic solution is injected about nerves, nerve trunks, or nerve plexuses. (05 Mar 2000) |
| nerve cell | An excitable cell specialised for the transmission of electrical signals over long distances. Neurons receive input from sensory cells or other neurons and send output to muscles or other neurons. Neurons with sensory input are called sensory neurons, neurons with muscle outputs are called motoneurons, neurons that connect only with other neurons are called interneurons. Neurons connect with each other via synapses. Neurons can be the longest cells known, a single axon can be several metres in length. Although signals are usually sent via action potentials, some neurons are nonspiking. (18 Nov 1997) |
| nerve cell body | The part of the neuron that includes the nucleus but excludes the processes. (05 Mar 2000) |
| nerve compression syndromes | Repeated or prolonged pressure on a nerve root or peripheral nerve leading to ischemia, the response to which is oedema above and below the source of pressure. If the pressure is not relieved, fibrosis tends to develop. Types of nerve compression syndromes are the neuropathy caused by intervertebral disk herniation, compression of the median nerve in the carpal tunnel, compression of the ulnar nerve in the elbow, and compression of the lateral cutaneous nerve of the thigh in meralgia paresthetica. This is also called pressure neuropathy. (12 Dec 1998) |
| nerve conduction | The transmission of an impulse along a nerve fibre. (05 Mar 2000) |
| nerve conduction velocity | The rate of impulse conduction in a peripheral nerve or its various component fibres, generally expressed in meters per second. (05 Mar 2000) |
| nerve deafness | Neural deafness, former terms for sensorineural deafness. (05 Mar 2000) |
| nerve decompression | Release of pressure on a nerve trunk by the surgical excision of constricting bands or widening of a bony canal. (05 Mar 2000) |
| nerve degeneration | Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways. (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) |
