Primary function of Oral Mucosa is:

• Sensation

• Secretion

• Thermal regulation

• Protection

• Conductivity

Keratohyaline granules are found in:

• Stratum granulosum

• Stratum spinosum

• Prickle cell layer

• Keratinized surface layer

Which of the following regions has a non-keratinized epithelium and is loosely attached to the

underlying structure:

• Buccal mucosa

• Attached gingiva

• Hard palate

• dorsum of tongue

• vestibular mucosa (lips)

Which of the following regions has a non-keratinized epithelium and is loosely attached to the

underlying structure:

• Buccal mucosa

• Attached gingiva

• Hard palate

• dorsum of tongue

• vestibular mucosa (lips)

The gingival area where nonkeratinized epithelium most frequently occurs and which,therefore,

may be considered most vulnerable to inflammation is the

• sulcular surface of the free gingiva

• palatal gingiva

• unattached gingiva

• buccal gingiva

• attached gingiva

The gingival area where nonkeratinized epithelium most frequently occurs and which,therefore,

may be considered most vulnerable to inflammation is the

• sulcular surface of the free gingiva

• palatal gingiva

• unattached gingiva

• buccal gingiva

• attached gingiva

The free gingiva is stippled when healthy.

• True
