Primary enamel cuticle
Encyclopedia
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. This tissue is primarily basal lamina
. It is usually worn away by mastication and cleaning.
Biological membrane
A biological membrane or biomembrane is an enclosing or separatingmembrane that acts as a selective barrier, within or around a cell. It consists of a lipid bilayer with embedded proteins that may constitute close to 50% of membrane content...

Tooth
Teeth are small, calcified, whitish structures found in the jaws of many vertebrates that are used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are embedded in the Mandible bone or the Maxillary bone and are...

Basal lamina
The basal lamina is a layer of extracellular matrix secreted by the epithelial cells, on which the epithelium sits. It is often confused with the basement membrane, and sometimes used inconsistently in the literature, see below....
