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.

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. From Dorland's, 2000.
Meckel's cartilage the ventral cartilage of the first branchial arch.
permanent cartilage cartilage that does not normally become ossified.
Reichert's cartilage the dorsal cartilage of the second branchial arch.
reticular cartilage elastic cartilage.
semilunar cartilage one of the two interarticular cartilages of the knee joint.
temporary cartilage cartilage that is normally destined to be replaced by bone.
thyroid cartilage the shield-shaped cartilage of the larynx, underlying the laryngeal prominence on the surface of the neck.
vomeronasal cartilage either of the two narrow strips of cartilage, one on each side, of the nasal septum supporting the vomeronasal organ.
yellow cartilage elastic cartilage.

car·ti·lage

(kar'ti-lij), [TA] Avoid the misspellings cartiledge, cartlage, and other variants.
A connective tissue characterized by its nonvascularity and firm consistency; consists of cells (chondrocytes), an interstitial matrix of fibers (collagen), and ground substance (proteoglycans). There are three kinds of cartilage: hyaline cartilage, elastic cartilage, and fibrocartilage. Nonvascular, resilient, flexible connective tissue found primarily in joints, the walls of the thorax, and tubular structures (for example, larynx, air passages, and ears); makes up most of the skeleton in early fetal life, but is slowly replaced by bone. For a gross anatomic description, see cartilago and its subentries.

Bajo este contexto, Laboratorios Expanscience lanza al mercado mexicano una alternativa como parte del compromiso con la salud de los mexicanos y presenta una alternativa a base de colageno hidrolizado, el cual es una proteina que facilita la formacion de diferentes tipos de colageno en el cuerpo humano para ser aprovechados en diferentes tejidos, para prevenir y retrasar el desgaste de las articulaciones, reducir el dolor, mejorar la movilidad y estimular la regeneracion del cartilago evitando el desgaste de las articulaciones, coadyuvando, asi, a mejorar la calidad de vida de los pacientes y su posible reincorporacion a su actividad laboral y/o fisica.
