Several molecules must work together for proper joint lubrication. In this illustration, the lubricin molecules anchor the long hyaluronan chains to the cartilage collagen network; these hyaluronan chains in turn attach the phospholipid molecules in either single layers (green) or double layers (blue)

A chicken heart muscle cell under a fluorescent microscope; the filaments consist of repeated subunits (bright dotted lines). The schematic representation shows three neighboring filaments; the black lines are the boundaries of their subunits, such that the lower filament is aligned with the middle one, while the upper one is not
