Fibrillar tis- sue in the form of elas- tic cartilage from the external ear of man. (After Bohm, Davidoff and Huber.) Like other connective tissues, fibrillar tissue (Fig. 100) consists of cells but it is distinguished principally by fibers that interlace among the cells. These fibers, themselves the product of cellular activity, are of two sorts, white non-elastic fibers, and yellow elastic fibers. The yellow fibers are pe- culiar to vertebrates. They occur in such parts of the body as the walls of the blood vessels, valves of the heart, the lining of the alveolae of the lungs, and in intervertebral ligaments. Both yellow and white fibers may be densely compacted together, as in fascia and sheaths of muscles, in peri- chondrium and periosteum, around cartilage and bone respectively, or they may be arranged in the form of looser texture, such as is found in the walls of blood vessels and the dermal part of the mammalian skin where they form the substance that is manufactured into leather. In the sclera of the eyeball and in tendons, between muscles and bones, the fibers are mostly white. Fibrillar tissue plays an indispensable part in holding things together and is probably the most widespread tissue in the vertebrate body. 2.
