costal cartilage

cartilage

[kahr´tĭ-lij] a specialized, fibrous connective tissue present in adults, and forming most of the temporary skeleton in the embryo, providing a model in which most of the bones develop, and constituting an important part of the organism's growth mechanism; the three most important types are hyaline cartilage, elastic cartilage, and fibrocartilage. Also, a general term for a mass of such tissue in a particular site in the body.

Involvement of joint and cartilage in osteoarthritis. From ARHP Arthritis Teaching Slide Collection, American College of Rheumatology.alar c's the cartilages of the wings of the nose.aortic cartilage the second costal cartilage on the right side.arthrodial cartilage (articular cartilage) that lining the articular surfaces of synovial joints.arytenoid c's two pyramid-shaped cartilages of the larynx.connecting cartilage that connecting the surfaces of an immovable joint.costal cartilage a bar of hyaline cartilage that attaches a rib to the sternum in the case of true ribs, or to the immediately above rib in the case of the upper false ribs.cricoid cartilage a ringlike cartilage forming the lower and back part of the larynx.diarthrodial cartilage articular cartilage.elastic cartilage cartilage that is more opaque, flexible, and elastic than hyaline cartilage, and is further distinguished by its yellow color. The ground substance is penetrated in all directions by frequently branching fibers that give all of the reactions for elastin.ensiform cartilage xiphoid process.fibrous cartilage fibrocartilage.floating cartilage a detached portion of semilunar cartilage in the knee joint.hyaline cartilage flexible, somewhat elastic, semitransparent cartilage with an opalescent bluish tint, composed of a basophilic fibril-containing substance with cavities in which the chondrocytes occur.

Hyaline cartilage. The matrix nearest the chondrocytes is intensely staining; although the matrix appears homogeneous, collagen fibrils may be visualized by polarized light or electron microscopy.
