Histology

Question 1

What are the layers of oral mucosa?

Answer 1

Stratum corneum - keratinised layer

Stratum granulosum

Stratum spinosum - prickle cell layer

Basal layer

Lamina propria

Submucosa

Question 2

What are the three types of oral mucosa?

Answer 2

Lining

Masticatory

Gustatory

Question 3

Typically what are the characteristics of masticatory mucosa?

Answer 3

mucosa that is subjected to friction or compression

Thick and tightly bound lamina propria so tissue is taught

Parakeratinised

Question 4

Typically what are the characteristics of lining mucosa?

Answer 4

Much more loosely attached to periosteum with flexible submucosa and lamina propria

Allows tissue to move more freely and be manipulated

Non keratinised

Faster cell turnover

Question 5

Typically what are the characteristics of gustatory mucosa?

Answer 5

Fungiform papilla

Filliform papilla

Vallate papilla in V shape at posterior border of tongue, also has a valley histologically around the papilla

Foliate papilla on the edge of the tongue
