==Introduction==

Ameloblasts are cells in the enamel organ which forms the tooth. They secrete [[Enamel - Anatomy & Physiology|enamel]].


==Properties==

[[Image:Ameloblast Histology.jpg|thumb|right|150px|Ameloblast Histology - Copywright RVC 2008]]
*Epithelial cells

*Lines the inner surface of the enamel organ

*Derived from epithelium

*Synthesises [[Enamel - Anatomy & Physiology|enamel]] which forms the [[Crown - Anatomy & Physiology|crown]] of each tooth

*Maintains connections with the newly synthesised [[Enamel - Anatomy & Physiology|enamel]] through cellular projections called Thomes' fibres

*[[Enamel - Anatomy & Physiology|Enamel]] is acellular so once the connection with the ameloblasts via the Thomes' fibres is lost (upon eruption), [[Enamel - Anatomy & Physiology|enamel]] matrix cannot be remodelled

*A single layer of very long columnar cells

*Hexagonal in cross section

*Elongated basally sited nuclei
