Anatomically, the model shows the skin's 2 layers, which are the epidermis and dermis. The skin (subcutis) is also seen.
The epidermis primarily consists of keratinocytes, and the model shows the layered structure which results from the displacement of these cells upwards towards the skin surface (see the different shapes of the cells). Furthermore, the basement membrane can be seen at the bottom.
The thick connective tissue layer with nerves, blood vessels and hair follicles with attached smooth muscle (m. arrector pili) can be seen in the dermis.
Some of the subcutaneous tissue is also shown in yellow at the bottom, which symbolizes fat cells (since the subcutaneous tissue mainly consists of fat cells).
The model's skin is divided into 6 "pillars" which cannot be separated. Each column shows both the epidermis, dermis and subcutaneous tissue. One column shows skin without disease, while the other 5 show mole cancer in different stages using darker cells (see images on the left).
All this means that the model can be used to understand the thickness of tumors via boats
Breslow level and Clark level.
Furthermore, there are 5 color images on the stand, which allow understanding of the English acronym ABCD (possibly + EFG), which is used in the clinical examination (where A means "Asymmetry", B means "Border", etc.).
