Abstract

The hairs of the skin not only function to prevent heat loss but also have important sensory functions. Recent work has now established that each hair of the skin is innervated by one or more of three types of mechanoreceptor ending. Each of these three mechanoreceptor types possesses distinct molecular features and detects distinctive information about skin touch, which is relayed to specific brain locations in a somatotopic fashion.

摘要

皮肤的毛发不仅具有防止热量散失的功能，还有着重要的感觉功能。最近的研究工作已经证实，皮肤的每根毛发都由一个或多个三种机械感受器末端神经支配。这三种机械感受器类型中的每一种都具有独特的分子特征，并检测到关于皮肤触摸的独特信息，这些信息以躯体定位的方式传递到特定的大脑区域。
