Relationship between structure and function of mammalian vibrissa
The structure of mammalian vibrissa was observed microscopically and the relationship of morphology and function was discussed. The vibrissa is conical. The elasticity and tenacity of vibrissa are stronger than that of pelage hair. The scales are shaped irregular on vibrissa shaft except for the root part, because of fractional damages. This type of scales is of great importance in preventing the vibrissa from being totally destroyed. Cortex of vibrissa is observed very well developed, thus its elasticity and tenacity work well in touching and sensing. Medulla of vibrissa is not well developed because vibrissa has been evaluated to fall in warm-keeping function.
