Flashcards in Chapter 5: Extracellular Structures Deck (8):
1

seal the spaces between cells and provide direct communication between cells

cell junctions

2

supports and protects cells and provides mechanical linkages between tissues

exracellular matrix (ECM)

3

glycoproteins in the plasma membrane that bind to specific molecules on other cells

cell adhesion molecules

4

regions of tight connections between membranes of adjacent cells

tight junctions

5

form buttonlike spots, or belts, that run entirely around cells, "welding" adjacent cells together

anchoring junctions

6

anchoring junctions with intermediate filaments that anchor the junction in underlying cytoplasm

desmosomes

7

microfilaments are the anchoring cytoskeletal component

adherens junctions

8

open direct channels that allow ions and small molecules to pass directly from one cell to another

gap junctions
