Anatomically, the model shows some hair and the skin's two layers, the epidermis and the dermis. The subcutis is also shown.
The epidermis consists primarily of keratinocytes, which create a layered structure due to their displacement upwards towards the skin surface. On the model, however, the epidermis appears uniform and without details.
Nerves, blood vessels, hair follicles with attached smooth muscle (m. arrector pili) and sweat and sebaceous glands are 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).
In addition, a pustule and 2 comedones (respectively open and closed) are seen, which characterizes acne.
Since the hair follicle and the sebaceous gland are also seen, the model can be used to understand the genesis of acne, which results, among other things, in occlusion of the follicle and retention of sebum and keratin.
