| 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. |

| 설명 | 카메라에 있어서 필름에 해당하는 눈의 망막은 크게 두 개의 층으로 나눌 수가 있다. 안쪽에 있는 실제의 빛을 감지하는 감각층과 바깥쪽의 외부의 빛을 차단하는 색소상피층이 그것인데 그 사이에는 잠재적인 공간이 있어서 떨어지기가 쉽다. 이 사이가 떨어지면 망막의 감각층이 망막의 색소상피층과 분리되는데 이것을 망막박리라고 한다. 이 망막의 박리에는 여러 가지 원인이 있지만 감각층의 망막에 작은 구멍인 열공(break)에 의해서 그곳으로 눈속을 채우고 있는 액체가 흘러 들어가서 생기는 망막의 박리를 열공성 망막박리(rhegmatogenous retinal detachment)라 하고, 안구의 병터에 의해서 안구내에 섬유조직이 생기고 그것이 망막의 감각층을 잡아 끌어서 망막이 박리되는 견인성 망막박리(traction retinal detachment) 및 망막의 2개의 층에 삼출액이 괴어서 생기는 삼출성 망막박리(exudative retinal detachment) 등 열공에 의해서 생기는 망막박리가 아닌 것을 비열공성 망막박리(nonrhegmatogenous retinal detachment)라고 말한다. |

| 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) |
