| desmosomes | cytoplasmic plauge + filaments. "spot" adhesions; strenghten. ex. cardiac muscle |
| gap junctions | cell to cell communication |
| simple squamos, 2 types, and function by... | endothelium, mesothelium, diffusion |
| endothelium | provides a friction reducing lining. found in hollow organs; blood vessels, heart, and lymphatic vessels |
| mesothelium | found in serious membranes; pleural, pericardial and peritoneal cavity, covers the visceral organs of those cavities |
| simple cuboidal | in ducts of glands, kidney tubules. functions in absorption/ secretion |
