Lateral Cell-Cell Adhesion established via:

Tight junctions (junctions are specialised modifications of cell surface in neighbouring cells)
Adherens junctions
Desmosomes
Gap junctions
Non-junctional adhesions (proteins such as cadherins, selectins, integrins)

Cell-Matrix Adhesion established via:

3 distinct classes of cell adhesion junctions:

Occluding (tight) junctions= forms a barrier between epithelial cells
Attachment junctions= links cell cytoskeleton to that of its neighbouring cell or to matrix
Communication junctions= directly connect cytoplasm of adjacent cells
