English to Italian Medical Medical (general) capelli e peli

Hair, Pili; longitudinal section through the scalp.
Hair is the product of keratinisation of the epidermis.
It originates from invaginations of the epidermis which form follicles that contain mitotically active cells (matrix cells) at the base.
The cells emerging from matrix cells diversify into horn cells, which form the hair shaft.
Postnatally, a distinction is made between two basic types of hair:
vellus hair (downy hair), which is soft, short (the follicles are in the dermis), thin and virtually unpigmented with no core; it corresponds to the fetal lanugo and covers most of the body in children and women
terminal hair (long hair), which is strong, long (the follicles reach the subcutis), thick and pigmented with a core; it occurs as scalp hair, eyelashes, eyebrows, pubic hair, armpit hair and beard hair (in men) and usually differs considerably in different ethnic groups.
Hair serves to protect against UV light and heat as well as to provide tactile sensation.
