What is the importance of the perichondrium that surrounds cartilage?
| A) It resists outward expansion when cartilage is subjected to pressure and functions in growth and repair of cartilage. |
| B) It helps to keep the cartilage avascular. |
| C) Cells in the perichondrium break down dead and dying cartilage cells and function in removing dead cartilage cells through the lymphatic system. |
| D) It forms the lacunae that surround chondrocytes. |
| E) It forms articular discs in the knee and jaw. |
Solution
The perichondrium located around the cartilage has many important and vital functions. The cartilage is a dynamic structure which remains in constant rigorous motion and highly prone to wear and tear. The perichondrium contains an outer layer of fibrous elastin which resists excessive outwards expansion of the cartilage. Also, a large number of nascent and dividing cartilagenous cells are located in the inner part of the perichondrium which help in growth, repair and wear and tear along with repair and maintenance of the cartilages.
Thus, according to this information, choice A is most correct.
