tissue CONNECTIVE TISSUE PROPER DENSE Elastic * 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 elastic fibers and they give the tissue a yellowish color. * Dense elastic connective tissue combines strength with elasticity : it can be stretched very easily and then recoils to its original length as soon as the tension is released. * It confers elastic properties which enable recovery of tissue shape following normal physiological deformation or stretching. * It is found in the * vocal cords, * in some ligaments (such as the ligamenta flava that connect adjacent vertebrae and the suspensory ligament of penis), * in the walls of elastic arteries, * in parts of the trachea and bronchi, and in the lung tissue. Cartilage Consist of a dense network of collagen and elastic fibers embedded in a firm matrix of chondroitin sulfate (a jellylike substance that provides support and adhesiveness in cartilage,
