pigment granule 色素粒。

pigment rayon

An ommatidium is composed of cornea , two corneagenous cells , four cone cells , eight retinular cells , rhabdom , distal pigment cells , distal and proximal reflecting pigment cells , in blue , red and in full bright light conditions , compound eyes exhibit obvious characters the disarrangement of microvilli in the rhabdom , the increased number of lamellar bodies , distal and proximal pigment granules covering the crystalline cone and rhabdom to prevent hard light damaging the ommatidia 現將我們的研究結果報道如下:日本沼蝦復眼屬于反射型重疊像眼,每一小眼由角膜,成角膜細胞( 2個) ,晶錐細胞( 4個) ,小網膜細胞( 8個)及其形成的感桿束和遠端色素細胞、遠端反光色素細胞、近端反光色素細胞組成。小眼角膜長方形,小眼密度為512個mm ~ 2 。

During dark adaptation , the rhabdomal figures are regular , the distal pigment granules and proximal pigment granules are concentrated in the distal of crystalline tract and the proximal rhabdom respectively , and while retinular pigment granules are lacked in proximal of ommatidium 暗適應時,感桿束外形規則,微絨毛排列整齊,遠端色素則集中于小眼的遠端,近端缺乏小網膜細胞色素,僅有近端反光色素分布。

The pigment granules are scarce and are seen in the upper and lower right corners of the image 整張片子除了右上角和右下角可見到少許金褐色色素顆粒外,其他部分幾乎看不到。

The pigment granules were more and located in distol part of the retinular cell 本實驗的研究證實細胞內儲存的caz ‘受到胞外c 。 ”
