WebCapillaries are lined by a layer of the flat endothelial cells bound together by an intracellular cement substance. A basement membrane surrounds capillary endothelial cells. A pericapillary sheath forms the outer wall of the capillary. In the pericapillary sheath there are branched Rouget cells or pericytes representing modified muscle cells.
