发现复眼中的晶锥、色素细胞、网膜细胞内含物及感杆,在这两个时刻的形态和结构有显著不同。
We found that there were various structural changes in cones, pigment cells, retinula cells, rhabdomeres at the two different times.
的细胞体、感杆和轴突较大,它与外周小网膜细胞R_(1~6)相同,其轴突终止在第一视神经节(薄板);
R_(7a) approximate many features of R_(1-6) cells, which have a larger, cell body, rhabdomere and axon, terminate in the first optic neuropil (lamina).
在果蝇这种较精密的复眼中,感杆小体彼此相隔,因此果蝇复眼的角分辨率显著提高,能够探测到较微小的运动物体。
In the more sophisticated eyes of flies, the rhabdomeres are separated, and as a result, fly eyes have significantly better angular resolution, and can detect smaller moving objects.
