|---|---|---|---|
| 설명 | 빛의 수용기로서, 두께 0.5~1mm의 그물모양구조를 이루며, 눈알의 신경부에 해당한다. 외측에 색소상피층, 시각세포(원뿔세포, 막대세포)의 층, 쌍극세포층, 신경절세포층, 가장 안쪽에는 신경섬유층이 있다. 눈에 들어온 빛은 신경섬유층, 신경절세포층, 쌍극세포층을 통과해 시각세포에 도달하며, 이곳에서 감광색소와 광화학적변화를 일으킨다. 이 변화를 쌍극세포로 전달하고 다시 중추로 전달하여 빛으로 감각된다. 망막의 부위에 따라 시각세포 분포가 달라, 황반이라고 불리는 부위에서는 원뿔세포만이 존재하며, 그 주위는 막대체세포가 많다. 시각신경이 들어오는 부위인 유두부에는 시각세포가 결여되어, 빛을 느끼지 않는다. 이것이 맹점이다. 망막 후부의 중앙에는 가장 예민한 황반이 있고, 황반의 중앙에는 막대시각세포가 없는 중심오목이 있다. 중심오목과 안쪽 약 0.25cm에는 시각신경 및 망막중심동맥이 들어가는 점이 있다. 이곳에서 망막은 불완전하며 맹점을 형성한다. |

| horizontal cells of retina | Cell's in the outer part of the inner nuclear layer of the retina that lie with their axes more or less parallel with the surface. They are thought to connect the rods of one part of the retina with cones of another part. (05 Mar 2000) |
|---|
| ganglion cells of retina | The nerve cell's of the retina whose central processes (fibres) form the optic nerve; their peripheral processes synapse with the bipolar cell's and through them with the rod and cone cell's; these cell bodies are round or flask-shaped and vary considerably in size. (05 Mar 2000) |

| pigment cells of retina | Cell's in the outermost layer of the retina that contain pigment granules. (05 Mar 2000) |
| palatine surface of horizontal plate of palatine bone | The inferior surface of the horizontal plate of the palatine bone. Synonym: facies palatina laminae horizontalis ossis palatini. (05 Mar 2000) |
| medial crus of the horizontal part of the facial canal | Medially-placed, anteriorly-directed first portion of the horizontal part of the facial canal. See: horizontal part of facial canal. Synonym: medial crus of the horizontal part of the facial canal. (05 Mar 2000) |
| great horizontal fissure | Horizontal fissure that divides the ansiform lobule into its major parts, crus I (superior semilunar lobule) and crus II (inferior semilunar lobule). Synonym: fissura horizontalis cerebelli, great horizontal fissure. (05 Mar 2000) |
| horizontal | 1. Pertaining to, or near, the horizon. "Horizontal misty air." 2. Parallel to the horizon; on a level; as, a horizontalline or surface. 3. Measured or contained in a plane of the horizon; as, horizontal distance. Horizontal drill, a drilling machine having a horizontal drill spindle. Horizontal engine, one the piston of which works horizontally. Horizontal fire, the fire of ordnance and small arms at point-blank range or at low angles of elevation. <physics> Horizontal force, the distance in a horizontal plane to which a gun will throw a projectile. Horizontal water wheel, a water wheel in which the axis is vertical, the buckets or floats revolving in a horizontal plane, as in most turbines. Origin: Cf. F. Horizontal.

| horizontal atrophy | A progressive loss of alveolar and supporting bone surrounding the teeth, beginning at the most coronal level of the bone. Synonym: horizontal resorption. (05 Mar 2000) |
| horizontal beam film | A radiograph made with the central axis of the X-ray beam parallel to the floor, able to show an air-fluid level. (05 Mar 2000) |
| horizontal cell | A type of nonspiking interneuron found in the retina, named for its morphology. Horizontal cells process the information from a large number of photoreceptors and synapse onto ganglion cells and other cell types in the retina. (18 Nov 1997) |
| horizontal cell of Cajal | A small fusiform cell found in the superficial layer of the cerebral cortex with its long axis placed horizontally. Synonym: Cajal's cell. (05 Mar 2000) |
| horizontal classification | <zoology> Classification which stresses grouping together taxa in a similar stage of evolution, rather than location on the same phyletic line. See: Vertical classification. (09 Jan 1998) |
| horizontal fissure of cerebellum | Horizontal fissure that divides the ansiform lobule into its major parts, crus I (superior semilunar lobule) and crus II (inferior semilunar lobule). Synonym: fissura horizontalis cerebelli, great horizontal fissure. (05 Mar 2000) |
| horizontal fissure of right lung | The deep fissure that separates the upper and middle lobes of the right lung. Synonym: fissura horizontalis pulmonis dextri, horizontal fissure of right lung, minor fissure. (05 Mar 2000) |
| horizontal fracture | A fracture of the facial bones in which there is a horizontal fracture at the base of the maxillae above the apices of the teeth. Synonym: horizontal fracture, Le Fort I fracture. (05 Mar 2000) |
| horizontal growth phase | An early stage of development of cutaneous melanoma by intraepidermal spread of atypical melanocytes. (05 Mar 2000) |
