They are located on the secretory, basal, end of the ameloblast.

More than one ameloblast contributes to a single prism.

Tomes' processes are those projections and give the ameloblast a "picket-fence" appearance under a microscope.

The secretory end of the ameloblast ends in a six-sided pyramid-like projection known as the Tomes' process.

Tomes' processes are a histologic landmark identified on an ameloblast, cells involved in the production of tooth enamel.

Each ameloblast is approximately 4 micrometers in diameter, 40 micrometers in length and has a hexagonal cross section.

During the synthesis of enamel, the ameloblast moves away from the enamel, forming a projection surrounded by the developing enamel.

The follicular type will have outer arrangement of columnar or palisaded ameloblast like cells and inner zone of triangular shaped cells resembling stellate reticulum in bell stage.

Primary enamel cuticle, also called Nasmyth's membrane, is thin membrane of tissue also known as reduced enamel epithelium produced by the ameloblast, that covers the tooth once it has erupted.

The reduced enamel epithelium, sometimes called reduced dental epithelium, overlies a developing tooth and is formed by two layers: a layer of ameloblast cells and the adjacent layer of cuboidal cells (outer enamel epithelium) from the dental lamina.
