10 Questions
What is the primary function of occluding junctions in cells?
To control the passage of material through the intercellular spaces
What is the characteristic feature of adhesive junctions in terms of their morphology?
They exist in two forms: deep to tight junctions and small circular patches called macula adherens (desmosomes)
What is the term used to describe the combination of zonula occludens, zonula adherens, and macula adherens?
Junctional complex
What is the size of the intercellular gap in communicating (gap) junctions?
2-3nm
What is the structure that forms the hollow tube-like channels in communicating (gap) junctions?

How do cells interact with each other through occluding junctions?
The cells come very close to each other and apparently fuse, leaving no intercellular spaces
What is the primary function of communicating (gap) junctions?
To provide channels of communication between the adjacent cells
What is the other name for occluding junctions?

What is the purpose of zonula adherens in cell-to-cell adhesion?
Forms a continuous band around the cell
