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

膀上布满了上百万个细如发丝感应器。

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，这一特殊细胞群上发状纤开始协调一致地跳动，指向后来会变成左侧部分。

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

通过破坏纤来实现，微小发状结构，其保持气道清洁。

The lung organoids, for example, had working lung cilia—hairlike structures that rhythmically beat to clear mucus and debris—just like the real thing.

例如，肺类器官具有正常工肺纤——有节奏地跳动以清除粘液和碎屑发状结构——就像真实东西一样。
