Question

Which of the following statement is not applicable to the structure of cartilage?

• A. Free surface of hyaline cartilage is covered by a fibrous cover called the perichondrium
• B. Chondrocytes are metabolically more active than chondroblasts
• C. The growth of cartilage is always unidirectional
• D. Hyaline cartilage forms the embryonic skeleton in bony vertebrates

Answer 1

The correct option is A Free surface of hyaline cartilage is covered by a fibrous cover called the perichondrium

Perichondrium is the layer made up of dense irregular connective tissue that is present on the exterior of the hyaline cartilage.

A. Perichondrium surrounds the cartilage externally.

B. Chondrocytes are responsible for making fibres and matrix of the cartilage. These are metabolically more active than the chondroblasts that are mesenchymal cells.

C. Cartilage always grows unidirectionally. Because of this healing of cartilage is a very slow process.

D. Hyaline cartilage is the most common type of cartilage in the bony vertebrates and it forms the embryonic endoskeleton. It is later ossified during the development of the foetus.

Hence, the correct answer is 'Free surface of hyaline cartilage is covered by a fibrous cover called perichondrium'.
