tissue CONNECTIVE TISSUE PROPER DENSE regular : * The fibroblasts are embedded in the matrix: they do not lie in lacunae (chambers within the matrix). * The fibers are densely packed and thus the ground substance is barely visible. * The fibers are primary collagenous fibers and are arranged parallel to each other (a few elastic fibers are also present in the matrix). This results in a white flexible tissue with great resistance to forces pulling in one direction. * The collagen fibers are slightly wavy: this allows the tissue to stretch a little until the fibers are straightened out but not more. * It is found in areas where tension is always exerted in a single direction, such as: * tendons (cords attaching muscles to bones), * aponeuroses (flat sheets attaching muscles to bones or to other muscles) * ligaments (attaching bones together at joints). * Ligaments contain more elastic fibers than do tendons and thus are slightly more stretchy.
