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.

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.

Histologically, control group showed normal articular cartilage (A), however osteoarthritic changes like surface irregularities and decreased number of chondrocyte were noted among group B1 (B1).
These regenerative therapies are safe and effective treatment options for osteoarthritis, with the potential to slow down the progression of osteoarthritis while promoting the regeneration of articular cartilage. The treatment is essentially a new paradigm in the treatment of osteoarthritis and one that decreases the need for surgical joint repair and replacement.
While the SAF is a focal defect of bone, the stellate crease is a focal defect of articular cartilage. It is located more medially within the acetabular roof than the SAF, immediately adjacent to the acetabular notch (Figure 5).
Articular cartilage was graded based on a modification of the Noyes and Stabler [13] classification system (Grade 0 = normal thickness and signal; Grade I = normal thickness but an altered signal; Grade II = superficial partial-thickness cartilage defect less than 50% of the total cartilage thickness; Grade III = deep partial-thickness cartilage defect more than 50% of the total cartilage thickness; and Grade IV = full-thickness chondral defect with exposure of subchondral bone).
The principal findings in our study were that insulin in combination with swim exercise completely blocked the rise in biomarkers of inflammation and oxidative stress beyond the control levels and substantially protected the integrity of the articular cartilage histology.
The response in articular cartilage in cases of traumatic injuries is related with how far the damage extends up to the subchondral bone.
[21-23] These studies, which primarily include healthy individuals without knee pain, have demonstrated that intense physical activity has beneficial effects on the articular cartilage of the knee [11,21] and reduces cartilage loss in healthy adults.
The principal purpose of articular cartilage is for offering a lubricated, smooth surface, decreasing the frictional coefficient and stresses sustained by the contacting joint surface, and facilitating the transmission of loadings to the underlying subchondral bone as indicated in Figure 1 [12-14].
Biomimetic scaffold is crucial in the reconstruction of connective tissue such as articular cartilage. Electrospinning may achieve the desired biomimetic characteristics with regard to biocompatibility and biomimicry by adding different synthetic and biological materials to the electrospinning nanofibers.
Specifically, the equine chondral defect models have been recognized to have specific advantages for translation into human articular cartilage regeneration [17-19].
A study comparing the MRI and corresponding arthroscopy reports in 139 military recruits reported false positive values ranging from 65% for the medial meniscus to 42% for the articular cartilage. Furthermore, 32% of surgically treated knees were normal, despite gross pathologic findings on MRI [7].
