The Langhan's cells present in the outermost of its five layers
The Langhan's cells present in the outermost of its five layers * still have a somewhat unknown function.  Those five layers include the lucidum, spinosum, granulosum, corneum, and the basalis, which is the deepest layer.  As older cells reach the outermost layer, they die and transform into squames, or scales of keratin.  FTP, name this region also home to the melanocytes as the outermost layer of the skin.
