Hyaline Cartilage
Question 1. Write a short note on perichondrium.
Answer.
- The perichondrium is a vascular membrane that forms the covering of a cartilage.
- It is made up of two layers:
- The outer fibrous layer is made up of collagen bundles. It has a rich blood supply.
- The inner chondrogenic layer is made up of chondroblasts. The chondroblast can change into chondrocytes. The chondroblasts can divide and secrete matrix, and it assists in the peripheral growth of the cartilage.

Question 2. Write a short note on the hyaline cartilage.
Answer.
It is the most widely distributed cartilage in the body.
Perichondrium Function
Histological features
- It is transparent (Greek, halos = transparent stone).
- It has a homogeneous, basophilic intercellular substance.
- It stains blue (i.e. basophilic) with hematoxylin and eosin stain due to the presence of chondroitin and keratin sulfate in its ground substance.

Hyaline Cartilage Structure
- The chondrocytes are present in groups of two to four cells within lacunae to form cell nests.
- The matrix around the cell nests is stained deeper to form a lacunar capsule. Groups of 2 or more chondrocytes are known as cell nests.
- The fibers are not seen as a distinct entity.
- It is covered by perichondrium.
