Hertwig epithelial root sheath initiates the formation of dentin in the root of a tooth by causing the differentiation of … Zobacz więcej Hertwig epithelial root sheath is derived from the inner and outer enamel epithelium of the enamel organ. Zobacz więcej The sheath is also responsible for multiple or accessory roots (medial growth) and lateral or accessory canals in the root (break in epithelium). It is controversial, but HERS may … Zobacz więcej Hertwig epithelial root sheath was not discovered in any mammalian species. Instead this epithelial structure was discovered by Oskar Hertwig in 1874 in an amphibian (see notes below for further discussion in other animals).
