| 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. |

| Arrhenius doctrine | The theory of electrolytic dissociation (1887) that became the basis of our modern understanding of electrolytes: in an electrically conductive solution (e.g., acid, base, or salt), free ions are present before electrolysis, and the proportion of molecules dissociated into ions can be calculated from measurements of electrical conductivity as well as of osmotic pressure. Synonym: Arrhenius law. (05 Mar 2000) |

| Monro-Kellie doctrine | A doctrine that states that the cranial cavity is a closed rigid box and that therefore a change in the quantity of intracranial blood can occur only through the displacement of or replacement by cerebrospinal fluid. Synonym: Monro-Kellie doctrine. (05 Mar 2000) |
| Monro's doctrine | A doctrine that states that the cranial cavity is a closed rigid box and that therefore a change in the quantity of intracranial blood can occur only through the displacement of or replacement by cerebrospinal fluid. Synonym: Monro-Kellie doctrine. (05 Mar 2000) |
| humoral doctrine | The ancient Greek theory of the four body humors (blood, yellow and black bile, and phlegm) that determined health and disease. The humors were associated with the four elements (air, fire, earth, and water), which in turn corresponded to a pair of the qualities (hot, cold, dry, and moist). A proper and evenly balanced mixture of the humors was characteristic of health of body and mind; an imperfect balance resulted in disease. Temperament of body or mind also was supposed to be determined, e.g., sanguine (blood), choleric (yellow bile), melancholic (black bile), or phlegmatic (phlegm). Synonym: fluidism, humoralism, humorism. (05 Mar 2000) |
| doctrine | 1. Teaching; instruction. "He taught them many things by parables, and said unto them in his doctrine, Hearken." (Mark iv. 2) 2. That which is taught; what is held, put forth as true, and supported by a teacher, a school, or a sect; a principle or position, or the body of principles, in any branch of knowledge; any tenet or dogma; a principle of faith; as, the doctrine of atoms; the doctrine of chances. "The doctrine of gravitation." "Articles of faith and doctrine." (Hooker) The Monroe doctrine, a policy enunciated by President Monroe (Message, Dec. 2, 1823), the essential feature of which is that the United States will regard as an unfriendly act any attempt on the part of European powers to extend their systems on this continent, or any interference to oppress, or in any manner control the destiny of, governments whose independence had been acknowledged by the United States. Synonym: Precept, tenet, principle, maxim, dogma. Doctrine, Precept. Doctrine denotes whatever is recommended as a speculative truth to the belief of others. Precept is a rule down to be obeyed. Doctrine supposes a teacher; precept supposes a superior, with a right to command. The doctrines of the Bible; the precepts of our holy religion. "Unpracticed he to fawn or seek for power By doctrines fashioned to the varying hour." (Goldsmith) Origin: F. Doctrine, L. Doctrina, fr. Doctor. See Doctor.

| bipolar neuron | A neuron that has two processes arising from opposite poles of the cell body. (05 Mar 2000) |
| magnocellular neuron | <anatomy, neurology> A neuron in the magnocellular region of the brain. Perhaps the first class of neuron from the central nervous system shown to be sensitive to nerve growth factor (that had previously been thought only to act at the periphery). (18 Nov 1997) |
| ganglionic motor neuron | See: motor neuron. (05 Mar 2000) |
| Mauthner neuron | <biology, marine biology> Large neuron in the mesencephalon of fishes and amphibians. A rare example of an individually identifiable neuron in a vertebrate nervous system. (18 Nov 1997) |

| cell adhesion molecules, neuron-glia | Cell adhesion molecules that mediate neuron-neuron adhesion and neuron-astrocyte adhesion. They are expressed on neurons and schwann cells, but not astrocytes and are involved in neuronal migration, neurite fasciculation, and outgrowth. Ng-cam is immunologically and structurally distinct from ncam (neural cell adhesion molecules). (12 Dec 1998) |

| cholinergic neuron | <physiology> Neurons in which actylcholine is the neurotransmitter. (15 Jan 1998) |
