From these are continued the nasal cartilages which form one-half to two-thirds of the external nose.
In the epiphysial cartilages and at the ossifying junctions, all the processes concerned in ossification, excepting the deposition of lime salts, occur to an exaggerated degree.
After fractures of costal cartilage or of the cartilages of the larynx the cicatricial tissue may be ultimately replaced by bone.
If the cartilages are sound, and if a movable joint is aimed at, they may be left; but if ankylosis is desired, they must be removed.
The articular cartilages are destroyed, the ends of the bones are covered with granulations, extra-articular abscesses form, and complete osseous ankylosis results.
Cartilage, on the other hand, being elastic, yields before the pressure, so that the intervertebral discs or the costal cartilages may escape while the adjacent bones are destroyed (Fig.
The articular cartilages may subsequently be transformed into connective tissue, with consequent fibrous ankylosis and obliteration of the joint.
The roughness due to fibrillation of the articular cartilages causes coarse friction on moving the joint, or, in the knee, on moving the patella on the condyles of the femur.
While all epiphysial cartilages contribute to this result, certain of them functionate more actively and for a longer period than others.

The neural arch develops from the basidorsal cartilages that rest upon, and at first are entirely distinct from, the perichordal sheath.
It rapidly spreads, and involves not only the pastern-bones, but the cartilages of the foot, and spreading around the pasterns and cartilages, thus derives its name.
From this joint the disease proceeds to the cartilages of the foot, and to the union between the lower pastern, and the coffin and navicular bones.
Whether the joint is large or small, the cartilages wear away and new bone is developed about the ends of the bones, so that the joint is large and mis-shapen, the fingers being knotted and the hands deformed.
Between the two cartilages is the joint cavity, while surrounding the joint is the capsule (fig.
When only one kind of movement (hinge) is allowed, as in the fruit bat, the cartilages are not found.

The cartilages enjoy a limited range of movement within the joint, passing backwards during flexion, and forwards again when the limb is extended; under normal conditions the lateral moves more freely than the medial.
It is most frequently a result of inherited syphilis, the nasal bones being imperfectly developed, and the cartilages sinking in so that the tip of the nose is turned up and the nostrils look directly forward.
While the limb is partly flexed, a slight degree of rotation of the leg at the knee is possible, and during this movement the cartilages glide from side to side, and the tibia rotates below them.

Extending backwards and downwards from the lateral margins of the epiglottis are the two ary-epiglottic folds which reach the arytenoid cartilages posteriorly.
The treatment consists in paring away the protuberant masses until the normal size and contour of the nose are restored, care being taken not to encroach on the cartilages or on the orifices of the nostrils.

If the skin-wound heals before the fibrous union of the tracheal cartilages is complete, exuberant granulations are apt to form and occlude the trachea, perhaps necessitating a new tracheotomy for dyspnea.
