I have been looking for a while for decient photographs of the top section of the skin. It is something I often want to use to illustrate a point. I am pretty sure I looked at Wikipedia ages ago, but I have just come across this stunning photo. And best of all, it is in the public domain so I can use it freely with a clear conscience, as indeed can you if you so desire. (The original Wikipedia article has it at a higher resolution, so get if from there if you have any serious use for it. Original Reference) Thanks to Kilbad for sharing it and congratulations on a superb bit of histology.
You can see very clearly the top layer of the skin, the stratum corneum, the epidermis populated with corneocytes sitting on top of the dermis.
