Extracellular matrix

Basal lamina AKA basement membrane

Fibrillar matrix

Cell junctions

Cell Junctions 1 & 2- Demosomes and hemidemosomes- Connect intermediate filaments in one cell to those in the next/extracellular matrix

Cell junctions 3: Tight junctions- seals gap between epithelial cells

Cell junction 4: Gap junctions- allows passage of small water soluble molecules from cell-cell.

Cell junction 5: Adherens junctions- involve cadherin in connecting actin filament bundle in one cell to that in the next

Cell junction 6: focal adhesion- involve integrin in their roles in cell movement, anchoring actin filaments in the cell to the extracellular matrix.
