| 영문 | cerebral concussion | 한글 | 뇌진탕 |
|---|---|---|---|
| 설명 | 외부에서 기원하는 물리적 충격으로 인해 뇌의 물리적 손상없이 일어나는 뇌의 기능 장애. 일시적으로 무의식, 반사소실, 등이 나타나지만 결국은 아무 후유증없이 정상으로 돌아온다. |

| 영문 | cerebral cortex | 한글 | 대뇌겉질 |
|---|---|---|---|
| 설명 | 대뇌의 표면부위를 대뇌겉질이라고도 한다. 대개 얕은회색질(superficial gray matter)와 동의어로 쓰인다. 회색질이란 대뇌의 표면에 신경세포가 모여있는 곳으로 회색을 띠는 부분을 말한다. 이와는 대조적으로 백색질이란 신경세포가 내는 신경섬유가 분포하는 곳이며 대뇌에서 회색질의 안쪽에 존재한다. 참고로 말하면 척수에서는 대뇌와 반대로 회색질 안쪽에 존재하고 백색질이 밖에 존재한다. 즉 척수에서는 신경세포가 척수의 안쪽에 존재하고 바깥쪽에 그 신경세포가 내는 신경섬유가 존재한다. |

| 영문 | cerebral artery | 한글 | 대뇌동맥 |
|---|---|---|---|
| 설명 | 대뇌의 혈액을 공급하는 동맥. 대뇌의 앞부분의 혈액을 공급하는 앞대뇌동맥(anterior cerebral artery), 중간부위의 혈액을 공급하는 중간대뇌동맥(middle cerebral artery), 뒷부분의 혈액을 공급하는 뒤대뇌동맥(posterior cererbral artery)의 세 가지가 있다. 대뇌는 크게 두 가지 동맥에 의해서 혈액을 공급받는다. 하나는 속목동맥(internal carotid artery)이고 하나는 척추동맥(vertebral artery)이다. 이 동맥들은 좌-우로 두 개씩 쌍을 이루어 뇌에 혈액을 공급한다. 척추동맥은 대동맥에서 나와서 목뼈에 있는 가로돌기구멍을 통해서 머리쪽으로 올라온다. 그리고는 두 개의 좌우 척추가 한 개로 합쳐져서 바닥동맥라는 동맥을 이룬다. 목동맥은 대동맥에서 기시하여 속목동맥과 바깥목동맥으로 나뉜다(나뉘기 이전을 온목동맥이라 한다). 바깥목동맥은 얼굴과 뇌를 제외한 머리의 부위에 혈액을 공급하는 혈관이고, 속목동맥은 뇌에 혈액을 공급한다.   |

| abapical pole | In an ovum, the pole opposite the animal pole (i.e., vegetal pole). (05 Mar 2000) |
|---|---|
| animal pole | <cell biology> In most animal oocytes the nucleus is not centrally placed and its position can be used to define two poles. That nearest to the nucleus is the animal pole and the other is the vegetal pole, with the animal vegetal axis between the poles passing through the nucleus. During meiosis of the oocyte the polar bodies are expelled at animal pole. In many eggs there is also a graded distribution of substances along this axis, with pigment granules often concentrated in the animal half and yolk, where present, largely in the vegetal half. (12 Nov 1997) |
| anterior pole of eyeball | The centre of the corneal curvature of the eye. Synonym: polus anterior bulbi oculi. (05 Mar 2000) |
| anterior pole of lens | The central point on the anterior surface of the lens of the eye. Synonym: polus anterior lentis. (05 Mar 2000) |
| vegetal pole | Of vertebrate eggs. The surface of the egg opposite to the animal pole. Usually the cytoplasm in this region is incorporated into future endoderm cells. (18 Nov 1997) |
| vegetative pole | The part of a telolecithal egg where the bulk of the yolk is situated. (05 Mar 2000) |
| germinal pole | <cell biology> In most animal oocytes the nucleus is not centrally placed and its position can be used to define two poles. That nearest to the nucleus is the animal pole and the other is the vegetal pole, with the animal vegetal axis between the poles passing through the nucleus. During meiosis of the oocyte the polar bodies are expelled at animal pole. In many eggs there is also a graded distribution of substances along this axis, with pigment granules often concentrated in the animal half and yolk, where present, largely in the vegetal half.

| medial pole of ovary | The rounded medial end of the ovary, usually directed toward the uterus. Synonym: extremitas uterina ovarii, medial pole of ovary. (05 Mar 2000) |
| Vitelline pole | <embryology> The vegetative pole of an ovum. (05 Mar 2000) |
| cephalic pole | The head end of the foetus. (05 Mar 2000) |
| pole | 1. A long, slender piece of wood; a tall, slender piece of timber; the stem of a small tree whose branches have been removed; as, specifically: A carriage pole, a wooden bar extending from the front axle of a carriage between the wheel horses, by which the carriage is guided and held back. A flag pole, a pole on which a flag is supported. A Maypole. See Maypole. A barber's pole, a pole painted in stripes, used as a sign by barbers and hairdressers. A pole on which climbing beans, hops, or other vines, are trained. 2. A measuring stick; also, a measure of length equal to 5 yards, or a square measure equal to 30 square yards; a rod; a perch. <botany> Pole bean, a horizontal timber resting on the tiebeams of a roof and receiving the ends of the rafters. It differs from the plate in not resting on the wall. Origin: As. Pal, L. Palus, akin to pangere to make fast. Cf. Pale a stake, Pact. 1. Either extremity of an axis of a sphere; especially, one of the extremities of the earth's axis; as, the north pole. 2. <geometry> A point upon the surface of a sphere equally distant from every part of the circumference of a great circle; or the point in which a diameter of the sphere perpendicular to the plane of such circle meets the surface. Such a point is called the pole of that circle; as, the pole of the horizon; the pole of the ecliptic; the pole of a given meridian. 3. <physics> One of the opposite or contrasted parts or directions in which a polar force is manifested; a point of maximum intensity of a force which has two such points, or which has polarity; as, the poles of a magnet; the north pole of a needle. 4. The firmament; the sky. "Shoots against the dusky pole." (Milton) 5. <geometry> See Polarity, and Polar, Magnetic pole. See Magnetic. <geography> Poles of the earth, or Terrestrial poles, the two opposite points on the earth's surface through which its axis passes. Poles of the heavens, or Celestial poles, the two opposite points in the celestial sphere which coincide with the earth's axis produced, and about which the heavens appear to revolve. Origin: L. Polus, Gr. A pivot or hinge on which anything turns, an axis, a pole; akin to to move: cf. F. Pole. Source: Websters Dictionary (01 Mar 1998) |
| pole cell | <cell biology> A cell at or near the animal or vegetal pole of an embryo. (18 Nov 1997) |
| pole fibre | <cell biology> Microtubules inserted into the pole regions of the mitotic spindle (each pole is the product of the division of the centrioles and constitutes a microtubule organising centre. (18 Nov 1997) |
| pole ligation | A ligation at the root of an organ to shut off or diminish blood supply. (05 Mar 2000) |
| posterior pole of eyeball | The centre of the posterior curvature of the eye. Synonym: polus posterior bulbi oculi. (05 Mar 2000) |
