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. This is the thing that above all others keeps your insides in.
