Solution
The correct option is D Cartilage
- Nervous tissue is well supplied with blood vessels.
- Muscle tissue has an abundant blood supply.
- Bone cells are embedded in a hard matrix that is made up of salts of calcium and phosphate. Bone is supplied with blood vessels through the haversian canal.
- Cartilage has widely spaced cells that are embedded in the matrix made of proteins and sugars. Cartilage has limited repair capabilities because chondrocytes are bound in lacunae and hence they cannot migrate to damaged areas. Therefore, cartilage damage is difficult to heal. Also, because hyaline cartilage does not have a blood supply, the deposition of the new matrix is slow.
