Collagen fibrils
This electron micrograph shows the loose connective tissue that lies beneath all epithelia. Individual collagen fibrils are visible in both longitudinal and cross section. Note the regular banding in the longitudinally oriented fibrils. In other areas, these fibrils can aggregate to form larger fibers and bundles. 25,000x
