Caption: Skin of black African. Light micrograph of a section through black skin, showing the dermis (bottom), basement membrane (black folded layer), epidermis (dark blue), and keratinised surface (top). The basement membrane and lower epidermis contain pigment-producing cells (melanocytes) that are highly active in black skin. These cells prod- uce the pigment melanin, which spreads through the epidermis giving the dark colour seen here. The upper epidermis consists mostly of dead cells toughened by the protein keratin to form a hard, protective layer. The dermis consists of living connective tissue containing blood vessels (bottom centre). Magnification x124 at 6x7cm size. Magnification: x160 at 6x9cm size.
