A. Hard tissues. Types of hard tissues. It is almost as resistant to tension as bone but somewhat less resistant to compression. It tends to deform under shear. Some calcified cartilage approaches bone in resistance to shear.
Cartilage is an avascular tissue.
When it becomes heavily calcified the chondrocytes die from malnutrition so repairs do not occur in calcified cartilage. Calcified - contains mineral deposits, may be almost as mineralized as bone. However the mineral lacks the precisely arranged crystal systems interspersed with regularly arranged cells seen in bone. Its rigidity is due to the hydrostatic pressure of its inflated cells within the notochordal sheath. In adult mammals it persists only as the gelloid pulp material of the intervertebral disks.
