| 영문 | retina | 한글 | 망막 |
|---|---|---|---|
| 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. |

| 영문 | venule | 한글 | 세정맥 |
|---|---|---|---|
| 설명 | 정맥보다 작은 혈관을 말함. 모세혈관(capillary)을 통해 각 세포에 영양과 가스교환을 시행한 혈액은 여기 소정맥에 모인 뒤, 정맥(vein)을 거쳐 대정맥(vena cava)으로 가게된다. |

| venule | <zoology> A small vein; a veinlet; specifically, one of the small branches of the veins of the wings in insects. Origin: L. Venula, dim. From vena vein. Source: Websters Dictionary (01 Mar 1998) |
| postcapillary venule | That portion of the blood circulation immediately downstream of the capillary network, the region having the lowest wall shear stress and the most common site of leucocytic margination and endothelial transmigration (diapedesis). (18 Nov 1997) |
