title: [Normal and mycotic nail].
abstract: Knowledge of anatomy and physiology of the nail unit is necessary to understand onychomycosis, their clinical patterns, and response to the different treatments. It was useful for the discovery of new transungueal products. In this chapter, we describe anatomy and physiology of the normal nail and the main routes of fungus entry that lead to the onychomycosis.
