觸覺是由嵌入皮膚的機械感覺神經元介導的，並將訊號從週邊傳遞到中樞神經系統。 在胚胎髮生過程中，軸突從這些神經元伸長以與發育中的皮膚接觸。 同時，皮膚上皮從同質組織轉變為由不同層和微區組成的異質器官。 在整個過程中，每個神經元末梢必須與適當的皮膚區域形成連結以發揮其功能。 這篇綜述介紹了哺乳動物皮膚感覺微域和支配它們的機械感覺神經元發育的最新知識。

We explain to children in detail how the skin is the location of the sense of touch which we use to learn about flavors of things. It tells children the sensation of touch is mediated by mechanosensory neurons that are embedded in skin and relay signals from the periphery to the central nervous system. During embryogenesis, axons elongate from these neurons to make contact with the developing skin. Concurrently, the epithelium of skin transforms from a homogeneous tissue into a heterogeneous organ that is made up of distinct layers and microdomains. Throughout this process, each neuronal terminal must form connections with an appropriate skin region to serve its function. This Review presents current knowledge of the development of the sensory microdomains in mammalian skin and the mechanosensory neurons that innervate them.
