苍蝇具有某些特殊的“分析能力”而引起科学家极大的兴趣。苍蝇的触觉器官有异常的敏感性,当它的腿刚一接触到任何东四的表面时,在这瞬息之间它就能对所接触的物貭表面进行精细的化学分析,以便“决定”停留与否。一切动物部具有神经末梢——化学感受器,当环境的化学组成发生变化时,这些感受器就能接受刺激。苍蝇腿上分布着很多化学感受器,布满密密的、由富于敏感性的神经纤维所组成的茸毛,它们能接受从物貭表面传来的信号并将 Flies have some special “analytical skills” which aroused great interest of scientists. The flies’ tactile organs are unusually sensitive and as soon as their legs come into contact with the surface of any TOSHIBA, it will be able to perform a delicate chemical analysis of the surface of the object in contact with it in the twinkling of an eye in order to “decide” Stay or not. All animal parts have nerve endings - chemoreceptors, which are stimulated when the chemical composition of the environment changes. There are many chemoreceptors in the fly’s legs, dense, insensitive nerve fibers that can receive signals from the surface of objects
