Integument


The integument (or skin) is the largest organ in the body. It has two layers: an outer epidermal layer and an inner (deeper) dermal layer. In this picture, the epidermal layer forms the bulk of the upper half of the image and the dermal layer forms the lower half of the image. The epidermis varies greatly in its thickness. In this particular area the epidermis is relatively thin, but on the palms of the hands and the soles of the feet, it can be much thicker. The deepest layer of the epidermis in this sample is heavily pigmented with melanin.
