Q

What type of boundary describes the connective tissue interface?

A

Wavy boundary: in most places in the body, the epithelium meets the connective tissue a wavy uneven manner.

Q

What is the function of the wavy boundary?

A

To increase the surface area for a strong adhesion to resist mechanical forces and increase nourishment for the epithelium.

Q

What is the difference between wavy boundary and smooth boundary?

A

There are no ridges or CT papillae such as an area found in the gingival tissues.

16
Q

What process can be distinguished as vulgarous and cicatircal?

A

Pemphigus

17
Q

What is pemphigus vulgarous?

A

Tissues are split at the desmosomes.

18
Q

What is pemphigus cicatrical?

A

Tissues are split between hemidesmosomes.

19
Q

What is the purpose of epithelial cell junctions?

A

They mechanically attach a cell to neighboring cells or to he basal lamina so that they can function as a strong structural unit.

20
Q

What are desmosomes?

A

Connection of two neighboring epithelial cells and their cytoskeletons together.

21
Q

What is a hemidesmosome?

A

Connection of epithelial cells to the basal lamina.
