Question

Cartilage is formed by____________.

Answer 1

Formation of cartilage:

1. Cartilage is formed from chondrocytes.
2. They are large mature round cells having surface projections.
3. Chondrocytes produce a combination of collagen, proteoglycans, and some other non-collagenous proteins.
4. The formation of cartilage from the mesoderm germ layer is called chondrogenesis.
5. Mesenchyme differentiates into chloroplasts. They secrete the major components of the matrix.
6. The matrix is a fluid-filled cavity that contains fibers and the protein chondrin.
7. Immature cartilage develops into a mature state as the initial chondrification occurs.
8. The size and mass of cartilage do not change significantly after initial chondrification as there is minimal cell division in cartilage.

Final answer: Cartilages are formed by chondrogenesis from chondrocytes.
