Tissue (Cell Junctions) Flashcards
1
Q
What do cell junctions do
A
-binds cells together
-neighbors plasma membrane
-linked by integral proteins
2
Q
What are the different types of cell junctions
A
Tight junctions, desmosomes, and gap junctions
3
Q
What do tight junctions do
A
-holds cell tightly together
-prevents macromolecules from passing between adjacent cells
-has integral proteins
-is in between cells of blood vessels
-acts like zipper
-some tight junctions are leaky in order for some substances to pass through
4
Q
What do desmosomes do
A
-has integral proteins
-acts like a button
-increases strength of tissue by holding cells together
5
Q
What do gap junctions do
A
-link adjacent cells
-are small pores in the cell membrane
-allows substances to pass through the cytosol of cells
