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.
Synonym(s): cartilago [TA], chondrus (1) , gristle

Los hallazgos detectados en las imagenes radiograficas fueron similares a los reportados por otros investigadores, incluyendo la presencia de reaccion periostica, destruccion del cartilago articular, compromiso del hueso subcondral, inflamacion de los tejidos blandos periarticulares y cambios de densidad de los componentes oseos de las articulaciones comprometidas.
Se aprecia diferenciacion de musculo estriado que corresponde a la lengua (1), hueso y cartilago mandibular del lado izquierdo (2), mesenquima (3), pequena cavidad oral (4).
De otra parte, el eccondroma diagnosticado por histopatologia es un tipo de condroma primario de hueso, el cual se divide en encondromas, que se originan desde la cavidad medular del hueso, y eccondromas, que surgen desde el cartilago en cualquier parte del esqueleto; ambas formas son raras en animales (Maxie 2007).
El uso de un dispositivo de adelantamiento mandibular provoca una actividad contractil en el musculo pterigoideo lateral que se traduce en un doble efecto mecanico y circulatorio sobre el cartilago condilar, lo que podria regular el desarrollo de este, corrigiendo las discrepancias maxilo-mandibulares originadas por micrognatismo mandibular anteroposterior.
De esta forma, la tecnica descrita puede emplearse en estudios de 1) descripcion del desarrollo del sistema esqueletico con fines pedagogicos; 2) correlacion de la aparicion de los centros de condrificacion y de osificacion con el crecimiento y desarrollo del organismo; 3) analisis de la correcta formacion del cartilago (condrogenesis) y del hueso (osteogenesis); 4) estandarizacion de biomodelos vertebrados de desarrollo del sistema esqueletico para estudios de embriologia y de anatomia comparada; y 5) estandarizacion de biomodelos mamiferos para el estudio de anomalias congenitas de origen medioambiental ante la exposicion de un posible agente teratogenico.
