MH 020a Pig Snout Fetal

Tooth Development

This fetal pig snout shows at the bell stage.

- overlies the tooth facing the oral cavity.
- arises by the condensation of mesenchymal cells on the central axis of the developing tooth.
- - loose connective tissue within the papilla.
Enamel Organ - epithelium formation that responsible for the production of enamel.
- - stellate cells that occupy the inner region of the enamel organ. It is mostly composed of fluid filled extracellular space.
- - forms the outer cell boundary.
- - forms the inner cell boundary.
- - several layers of squamous cells on the surface of inner enamel epithelium.
- simple columnar cells that produce predentin. Their basophilic cytoplasm faces the layer of dentin.
- - light staining, unmineralized matrix between odontoblasts and the layer of dentin.
- - basophilic, mineralized matrix between odontoblasts and ameloblasts.
- simple columnar cells that produce enamel.
