Dense irregular connective tissue
This electron micrograph of dense irregular connective tissue demonstrates large collagen bundles, composed of numerous collagen fibrils, and dark elastic fibers criss-crossing the tissue. An active fibroblast, which synthesizes both elastic and collagen fibers, is present in the lower part of the image. Dermis of the skin 5000x
