摘　　要：The Structure of mammalian vibrissa was observed microscopically and the relationship of morphologyand function was discussed. The vibrissa is conical. The elasticity and tenacity of vibrissa are stronger than that ofpelage hair. The scales are shaped irregular on vibrissa shaft except for the root part, because of tractional damages. This type of scales is of great importance in preventing the vibrissa from being totally destroyed. Cortex ofvibrissa is observed very well developed, thus its elasticity and tenacity work well in touching and sensing. Medullaof vibrissa is not well developed because vibrissa has been evaluated to fail in warm-keeping function.The structure of mammalian vibrissa was observed microscopically and the relationship of morphology and function was discussed.
