This item is composed of four different models on the same base: the first one is a longitudinal section, 100X life size, of the hair root. The other three models are cross sections, greatly enlarged, of the hair shaft, hair root and hair bulb. The use of unauthentic colours makes it easy to identify all the diff erent layers, such as external and internal root sheath, cuticle and cortex, that make up the hair.
Mounted on board.
