A Quetzalcoatlus wing is covered with millions of tiny hairlike sensors.

它的翅膀上布满了上百万个细如发丝的感应器。

It does this by damaging the cilia, tiny hairlike structures whose job it is to keep the airways clean.

它是通过破坏纤毛来实现的，微小的毛发状，作是道清洁。

The process is subsequently repeated with hairlike filaments and blunt needles in order to establish the patients' sensitivity to pressure.

随后毛发状细丝和钝针重复该过程，以确定患者对压力的敏感性。

Last year researchers found that hairlike cilia on this special bunch of cells began to beat in unison, pointing toward what will later become the left side.

去年，研究人员发现，这一特殊细胞群上的毛发状纤毛开始协调一致地跳动，指向后来会变成左侧的部分。
