Which nail structure consists of nerves and blood vessels that supply moisture and nourishment to the nail plate?

The nail bed is the structure that contains nerves and blood vessels, which are essential for supplying moisture and nourishment to the nail plate. This living tissue lies beneath the nail plate, providing an important foundation and support for nail growth. The blood vessels in the nail bed ensure that the nail plate receives oxygen and nutrients necessary for its health, while the nerves can help with sensation.

The nail plate, in contrast, is primarily composed of keratin and forms the hard, visible part of the nail that extends beyond the fingertip. The nail matrix is responsible for producing the cells that form the nail, while the cuticle acts as a protective barrier at the base of the nail. While all these structures contribute to the overall health and appearance of the nail, it is the nail bed that plays the critical role in nourishment and moisture.
