Structure of hair. Illustration of the structure of a strand of hair and its protein keratin. Units of keratin combine to form microfibril, which in turn form macrofibrils. The strand has a central medulla, surrounded by a cortex. The outer layer is the cuticle. For this illustration with and without the fibril structure, and with and without labels, see images C047/5291 to C047/5294.
