The cells that produce most of the matrix of cartilage are called ______.

• A. chondrocytes
• B. fibroblasts
• C. osteocytes
• D. adipocytes

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the context of the question. The matrix of cartilage is a specialized connective tissue that provides support and flexibility in various parts of the body, such as joints, ears, and nose.
2. Step 2: Recall the types of cells involved in connective tissues. Chondrocytes are the cells responsible for producing and maintaining the cartilage matrix. Fibroblasts produce fibers and ground substance in connective tissue, osteocytes are bone cells, and adipocytes store fat.
3. Step 3: Focus on the specific function mentioned in the question: producing the matrix of cartilage. This function is unique to chondrocytes, as they secrete the extracellular matrix components like collagen and proteoglycans.
4. Step 4: Eliminate incorrect options based on their functions. Fibroblasts are involved in general connective tissue, osteocytes are involved in bone tissue, and adipocytes are involved in fat storage. None of these produce cartilage matrix.
5. Step 5: Conclude that the correct answer is chondrocytes, as they are the specialized cells responsible for producing most of the matrix of cartilage.
