Fig 2.6 Cross-section of a nail

The nail is an important appendage of the skin and is an extension of the stratum lucidum (clear layer) of the epidermis. It is composed of horny flattened cells which undergo a process of keratinisation, giving the nail a hard appearance. It is the protein keratin which helps to make the nail a strong but flexible structure. The part of the nail the eye can see is dead as it has no direct supply of blood, lymph and nerves. All nutrients are supplied to the nail via the dermis.
