Skin of penis. Coloured scanning electron micrograph (SEM). The skin of the penis is more heavily pigmented than that of the rest of the body. It is connected to the underlying fascias by loose connective tissue. The layers of the keratinised squamous epithelium are revealed by a tissue fracture. Nuclei of the keratinocytes are also visible. Magnification: x300 when printed 10 centimetres wide
