The Hertwig epithelial root sheath (HERS) or epithelial root sheath is a proliferation of epithelial cells located at the cervical loop of the enamel organ in a developing tooth. Hertwig epithelial root sheath initiates the formation of dentin in the root of a tooth by causing the differentiation of odontoblasts from the dental … 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 … 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). Zobacz więcej While in mammals the HERS is rather a transient structure, in amphibians it is more or less a permanent one.

WitrynaWhat is Hertwig's Epithelial Root Sheath? HERS is a bilayer of epithelial cells covering the connective tissue of the developing root. What is the epithelial diaphragm? The epithelial diaphragm is the part of the HERS underneath the developing crown. What forms first, lateral component of HERS or epithelial diaphragm? Epithelial diaphragm. Witryna3 sty 2024 · The Hertwig’s epithelial root sheath (HERS) is a bilayer epithelial sheath originated from the apical region of the enamel organ [ 5 ]. As for the process of tooth root development, HERS plays an important role in guiding root formation and determining the size, shape, and number of tooth roots [ 6 ].
