• papillae layer

What does the submucosa contain

(a)  

What us the sub-epithelial connective tissue

• basale cell layer

• submucoas

• Lamina Propria

• papillary layer

What is the papillary layer

• projections up and down to connect the layers

• has high blood vessels for absorption

• top layer of the skin

what is the submucoas

• contains loose fatty tissue

• contains blood vessels

• present in tongue, bottom of mouth, soft palate

• present in cheeks, lips, and places or hard palate

• separates the oral mucosa from the underlying bone or muslces

oral mucoperisteum

• attaches to submucosa

• attaches directly to underlying bone

• provides elastic attachments

• provides inelastic attachment

• present in gingiva and parts of hard palate
