Fig. 232. Longitudinal section through a developing hair from a five and one-half months fetus
As development proceeds and the hair anlage pushes deeper into the corium, its base enlarges into the bulb which becomes moulded over the papilla (Fig. 232). The actual hair substance is a proliferation from the basal epidermal cells next the papilla. These cells give rise to an axial core, destined to become the inner sheath and shaft, which grows toward the surface (Fig. 232). Entirely distinct are the peripheral cells of the original anlage which constitute the outer sheath.
