Junctional Epithelium Attachment :]

Hey guys, could someone please tell me how the junctional epithelium is attached to both the tooth surface and the lamina propria?

thanks!

The JE interface with Gingival CT (lamina propria), In a case where the patients oral health is sound, the JE would have a smooth tissue interface with the CT (ie. no wavy junctions)
The epithelial cells of the JE attach to the underlying gingival CT through hemidesmosomes and the external basal lamina of the JE. Similarly the JE attaches to the tooth surface using hemidesmosomes and the INTERNAL basal lamina of the JE!

Hope that makes sense
