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

*Epithelial cells
 
 
 
*Lines the inner surface of the enamel organ
 
 
 
*Derived from epithelium
 
 
 
*Synthesises [[Enamel|enamel]] which forms the [[Crown|crown]] of each tooth
 
 
 
*Maintains connections with the newly synthesised [[Enamel|enamel]] through cellular projections called Thomes' fibres
 
 
 
*[[Enamel|Enamel]] is acellular so once the connection with the ameloblasts via the Thomes' fibres is lost (upon eruption), [[Enamel|enamel]] matrix cannot be remodelled
 
 
 
*A single layer of very long columnar cells
 
 
 
*Hexagonal in cross section
 
 
 
*Elongated basally sited nuclei
