| 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. |

| Purkinje cell | <neurology, pathology> A class of output neurons in the cerebellum, which are the only neurons that convey signals away from the cerebellum. They form a layer of large ganglion cells near the surface of the cerebellum. Origin: From J. E. Purkinje, their discoverer. (12 Dec 1998) |

| Purkinje conduction | <neurology, physiology> Conduction of the cardiac impulse through the Purkinje system. (05 Mar 2000) |
| Purkinje effect | <ophthalmology> In the light-adapted eye, the region of maximal brightness is in the yellow; in the dark-adapted eye, the region of maximal brightness is in the green. Synonym: Purkinje effect, Purkinje shift. (05 Mar 2000) |
| Purkinje fibre | <cardiology, pathology> A group of specialised cardiac muscle cells that conduct electrical impulses through the heart and are involved in regulating the heart beat. The fibres form the terminal portion of the heart conduction system and have central granulated protoplasm containing one or two nuclei and a transversely striated peripheral portion. They are the terminal ramifications of the conducting system of the heart found beneath the endocardium of the ventricles. See: conducting system of heart. (10 Jul 2002) |
| Purkinje images | <ophthalmology, physiology> The two images formed by the anterior and posterior surfaces of the cornea and the two images formed by the anterior and posterior surfaces of the lens. Synonym: catatropic image, Purkinje images, Sanson's images. (05 Mar 2000) |

| Purkinje's figures | <ophthalmology> Shadows of the retinal vessels, seen as dark lines on a reddish field when a light enters the eye through the sclera and not the pupil. (05 Mar 2000) |
| Purkinje shift | <ophthalmology> In the light-adapted eye, the region of maximal brightness is in the yellow; in the dark-adapted eye, the region of maximal brightness is in the green. Synonym: Purkinje effect, Purkinje shift. (05 Mar 2000) |
| Purkinje's layer | The layer of Purkinje cells between the molecular and granular layers of the cerebellar cortex. Synonym: stratum neuronorum piriformium, ganglionic layer of cerebellar cortex, layer of piriform neurons, Purkinje's layer, stratum gangliosum cerebelli. (05 Mar 2000) |
