摘要
昆虫的复眼是昆虫最重要的光感受器,复眼是由一个个独立的小眼构成的,每个小眼主要是由角膜、晶锥、感杆束、色素细胞、基膜等组成。角膜和晶锥构成了复眼的屈光器,主要是起到透光、保护感受器和屈光的作用。感杆束和色素细胞可以随着光强的变化而变化,起到调节光量的作用,同时还起到视觉定向功能的作用。基膜是连接小眼和视神经的部分,起到了增加视神经感受性和支撑小眼的作用。
The compound eyes of insects are the most important photoreceptors, that is composed by rome independent ommatidia. Every ommatidia is composed of cornea, crystalline cone, rhabdom, and pigment cells. Cornea and crystalline cone composed the dioptric apparatusof the eye, played a role in light transmission, dioptric and protect the receptor. Rhabdom and pigment cells charge with the light intensity changes, not only play a role in regulating the quantity of light, but also play a role in the function of visual orientation. Basement membrane which connected the ommatidia and the optic nerve have increased the susceptibility and supported the role of the ommatidia.
