| 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. |

stratum compactum
| neuroepithelial layer of retina | The outermost layer of the cerebral layer of retina, composed of the primary receptor cells of the retina; the stratum consists of two sublayers: 1) an external layer made up of the rods and cones, the photosensitive processes of the receptor cells, and 2) the external nuclear layer containing the cell bodies of these cells; the external limiting membrane forms a perforated supporting plate between the two sublayers; the name refers to the fact that the retinal receptor cells are a specialised form of (epithelial) ependyma cell and thus, in a sense, are comparable to the neuroepithelial cells (e.g., hair cells) of other sense organs. Synonym: external nuclear layer of retina, stratum neuroepitheliale retinae, stratum nucleare externum retinae. (05 Mar 2000) |

| neoplasms, neuroepithelial | Neoplasms composed of epithelial cells of the nervous system. This concept does not refer to neoplasms located in the nervous system, nerves, or neural tissue. (12 Dec 1998) |
| neuroepithelial | Relating to the neuroepithelium. (05 Mar 2000) |
| neuroepithelial body | A corpuscular aggregate of nonciliated cells containing neurosecretory substance found in normal bronchial epithelium. (05 Mar 2000) |
| neuroepithelial cells | neuroectoderm |
| dysembryoplastic neuroepithelial tumour | A rare low grade neoplasm most frequently seen in children and associated with seizures and cortical dysplasia; the often multinodular, multicystic tumour is comprised of an oligodendroglial-like background with accompanying neurons. (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) |
| ganglionic layer of retina | The intermediate layer of neurons in the retina composed largely of bipolar cells. Synonym: internal nuclear layer of retina, stratum ganglionare retinae, stratum nucleare internum retinae. (05 Mar 2000) |
| medial arteriole of retina | An arteriole supplying the part of the retina between the optic disk and the macula. Synonym: arteriola medialis retinae. (05 Mar 2000) |
| medial venule of retina | The small vein that passes from the part of the retina between the macula and the optic disk to join the central vein. Synonym: venula medialis retinae. (05 Mar 2000) |
| central artery of retina | A branch of the ophthalmic artery which penetrates the optic nerve 1 cm behind the eye to enter the eye at the optic papilla in the retina; it divides into superior and inferior temporal and nasal branches. Synonym: arteria centralis retinae, arteria retinae centralis, Zinn's artery. (05 Mar 2000) |
| central vein of retina | Formed by union of the retinal veins and accompanies the artery of the same name in the optic nerve. Synonym: vena centralis retinae. (05 Mar 2000) |
| cerebral layer of retina | The internal layer of the retina containing the neural elements, as distinguished from the outer leaf of the retina, or pigmented layer. Synonym: pars optica retinae, neural layer of retina, optic part of retina, stratum cerebrale retinae. (05 Mar 2000) |
| retina | Light sensitive layer of the eye. In vertebrates, looking from outside, there are four major cell layers: (i) the outer neural retina, which contains neurons (ganglion cells, amacrine cells, bipolar cells) as well as blood vessels, (ii) the photoreceptor layer, a single layer of rods and cones, (iii) the pigmented retinal epithelium (PRE or RPE), (iv) the choroid, composed of connective tissue, fibroblasts and including a well vascularised layer, the chorio capillaris, underlying the basal lamina of the PRE. Behind the choroid is the sclera, a thick organ capsule. In molluscs (especially cephalopods such as the squid) the retina has the light sensitive cells as the outer layer with the neural and supporting tissues below. See: retinal rods, retinal cones, rhodopsin. (18 Nov 1997) |
