English to Italian Medical Medical (general) follicolo pilifero

La figura descrive la struttura di un follicolo pilifero.

Each hair follicle has a sebaceous gland (pilosebaceous gland unit) and a smooth muscle (musculus arrector pili) associated with it.
The latter is responsible for erection of the hair (sympathetic activation) whereby the epidermis is retracted, forming small pits (goose bumps).
A distinction is made between:
the fully keratinised hair shaft with an epithelial hair root sheath
the non-keratinised hair root, separated by the keratogenous zone (keratinisation of hair cells) from the keratinised hair shaft
the hair bulb (bulbus pili), the distended epithelial initial part of the hair, which contains cell division – enabling matrix cells
