| 설명 | 하나의 신경세포를 이른다. 신경세포의 구조는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 즉 위에서 전해져 내려오는 신경자극은 가지돌기를 통해 받아져서, 그 신경세포 막을 따라 전기적 자극으로 바뀌어져 내려가게 된다. 수상돌기에서 세포체, 그리고 축삭으로 건내어져 신경종말에 이르러 근육이나, 혹은 다른 신경조직으로 전달되어 지는 것이다. 이때 축삭주위에는 절연체인 말이집(myelin sheath)가 둘러싸여져 있고 각 수초사이에는 절흔이 존재하는데 이것을 란비에 결절(Ranvier's node)이라 부른다. 신경전달이 빨리 이루어지도록 하기위해 고등생물에 존재하는 란비에 결절은 이 결절들사이로만 신경전달이 이루어져 보다 빠른 전달이 일어난다. 신경세포의 분류는 주로 기능이나, 혹은 그 전달의 방향에 따라 분류하지만, 말초신경중 중요한 신경이나, 중추신경은 각기 그 명칭이 정해져 있다. 즉, “운동신경(운동을 담당하는 신경조직. 주로 사지말단에 분포한다)”, “감각신경(감각을 담당하는 신경조직으로 통각, 온도감각, 촉각 등을 뇌로 전달해주는 역할을 한다)” 등으로 불리워지거나, 또는 “들신경(밖에서 안으로 유입된다는 뜻으로 주로 감각신경을 뜻한다)” “날신경(안에서 바깥으로 작용을 가하기위해 나간다는 뜻으로 주로 운동신경이나 자율신경을 뜻한다)”등으로 불리워 지고, 중요한 신경인 경우는 정강신경, 종아리신경 등으로 고유명칭이 붙여져 있다 신경세포를 이루고 있는 모든 부분에서 이상이 나타날 수 있으며, 이때 신경체나 혹은 신경핵의 손상은 중추신경계(주로 뇌에서 직접 분지되어 내려온 신경을 말함)에서는 재생될 수 없으며, 주위 수초 등에 의한 병터에서는 재생이 가능하다. |

| local circuit theory | <physiology> A generally accepted model for neuronal conduction, by which depolarisation of a small region of a neuronal plasma membrane produces transmembrane currents in the neighbouring regions, tending to depolarise them. As the sodium channels are voltage gated, the depolarisation causes further channels to open, thus propagating the action potential. (18 Nov 1997) |

| anaesthesia, closed-circuit | Inhalation anaesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anaesthetic gas and oxygen are added so that no anaesthetic escapes into the room. Closed-circuit anaesthesia is used especially with explosive anaesthetics to prevent fires where electrical sparking from instruments is possible. (12 Dec 1998) |
| anaesthetic circuit | Equipment used during inhalation anaesthesia to regulate concentrations of inhaled gases; includes a reservoir bag and usually directional valves, breathing tubes, and a carbon dioxide absorber. (05 Mar 2000) |
| break-circuit | <physics> A key or other device for breaking an electrical circuit. Source: Websters Dictionary (01 Mar 1998) |
| Papez circuit | A long circuitous conduction chain in the mammalian forebrain, leading from the hippocampus by way of the fornix to the mammillary body and thence returning to the hippocampus by way of, sequentially, the anterior thalamic nuclei, cingulate gyrus, and parahippocampal gyrus. (05 Mar 2000) |
| reverberating circuit | A theory of periodic conduction through the cerebral cortex of trains of impulses traveling in circuit's of neurons. (05 Mar 2000) |
| circuit | The path or course of flow of cases or electric or other currents. Origin: L. Circuitus, a going round, fr. Circum, around, + eo, pp. Itus, to go (05 Mar 2000) |
| closed circuit method | A method for measuring oxygen consumption in which the subject rebreathes an initial quantity of oxygen through a carbon dioxide absorber and the decrease in the volume of oxygen being rebreathed is noted. (05 Mar 2000) |
| short-circuit | <physics> A circuit formed or closed by a conductor of relatively low resistance because shorter or of relatively great conductivity. <physics> To join, as the electrodes of a battery or dynamo or any two points of a circuit, by a conductor of low resistance. Origin: Short-circuited; Short-circuiting. Source: Websters Dictionary (01 Mar 1998) |
| open circuit method | A method for measuring oxygen consumption and carbon dioxide production by collecting the expired gas over a known period of time and measuring its volume and composition. (05 Mar 2000) |
| anaesthesia, local | Anaesthesia confined to one part of the body. Infiltration anaesthesia produces local anaesthesia by deposition of a local anaesthesia solution in the area of small, terminal nerve endings. (12 Dec 1998) |
| anaesthetics, local | Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fibre. In contact with a nerve trunk, these anaesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. Nearly all local anaesthetics act by reducing the tendency of voltage-dependent sodium channels to activate. They are commonly used not only in the peripheral nervous system, but also for spinal anaesthesia. The many drugs that have local anaesthetic actions as a side effect but are not used for their local anaesthetic action are not included here. (12 Dec 1998) |
| anti-infective agents, local | Substances used on humans and other animals that destroy harmful microorganisms or inhibit their activity. They are distinguished from disinfectants, which are used on inanimate objects. (12 Dec 1998) |
| neoplasm recurrence, local | The local recurrence of a neoplasm following treatment. It arises from microscopic cells of the original neoplasm that have escaped therapeutic intervention and later become clinically visible at the original site. (12 Dec 1998) |
| local | Restricted to or pertaining to one spot or part, not general. Origin: L. Localis (18 Nov 1997) |
