| 설명 | 안구의 각막과 수정체 사이에 있는 둥근 모양의 얇은 막. 막의 중앙에 동공이 있으며, 홍채의 신축으로 동공이 축소되거나 확대되어 안구에 들어오는 빛의 양을 조절한다. 인종에 따라 색소가 다른다. 눈동자의 주위에 있는 고리 모양의 막, 검은 눈동자의 본체는 각막을 통해 흑색으로 보이는 홍채이다. 중앙에 원형의 동공이 있고, 이 곳을 통하여 전안방과 후안방이 이어진다. 홍채가 이완하거나 수축함에 따라 동공의 크기가 변하고 따라서 망막에 달하는 광선의 양이 조절된다. 즉, 홍채는 카메라의 조리개에 해당한다. 홍채의 이완과 수축은 그 속에 있는 동공산대근 및 동공조임근에 의하여 이루어진다. 홍채의 외주연은 섬모체연이라고 하며, 모양체에 연결되어 있다. 또 내측연, 즉 동공의 외주연은 동공연이라고 한다. 홍채의 조직은 색소세포가 풍부한 층으로 되어 있는데, 그 색소의 빛깔이나 혈관의 다소에 의하여 홍채의 빛깔이 달라 보인다.  |
