In human anatomy, the eponychium or cuticle is the thickened layer of skin surrounding fingernails and toenails. Beneath the cuticle is a thin layer of a membrane known as the pterygium. The function is to protect the area between the nail and epidermis from exposure to harmful bacteria.
The vascularization pattern is similar to that of perionychium.[1]
