• A. Matrix
• B. Plasma
• C. Perichondrium
• D. All of the above

Answer 1

Answer: (C)

Perichondrium

Regeneration of cartilage can occur from its perichondrium. The perichondrium is a layer of dense irregular connective tissue that surrounds the cartilage of developing bone. It consists of two separate layers: an outer fibrous layer and inner chondrogenic layer. The fibrous layer contains fibroblasts, which produce collagenous fibers. The chondrogenic layer remains undifferentiated and can form chondroblasts or chondrocytes. It also functions in the growth and repair of cartilage.

Hence the correct option is C.
