Description
Heel skin tissue. Polarised light micrograph of a transverse section through skin from the heel of a human foot. The sole of the foot has to withstand the weight of the body and friction when the foot pushes against the substratum. To cope with this, the outer epidermis forms deep layers of dead keratinised cells (red and blue) which are replaced from the meristematic Malpighian layer as they get worn away. The dermis (yellow and green) consists of collagenous elastic fibres. Magnification: x103 when printed at 10 centimetres high.
