NDAEB exam review- ORAL ANATOMY 2.1.
The entire oral cavity is lined with ______ ______tissue. This type of tissue is moist and is adapted to

orange.
_______ _____,

The,______ ______ is the extension of the free gingiva that fills the interproximal embrasure between
two adjacent teeth.
also known as " interdental papilla"
interdental gingiva
The _____ _____ is a shallow groove that runs parallel to the margin of the unattached gingiva and
marks the beginning of the attached gingiva.
gingival groove
, The _____ _____ extends from the base of the sulcus to the mucogingival junction. It is a stippled,

Oral cavity proper
The ____ ______separates the nasal cavity above from the oral cavity below
