Which cell type is involved in the maintenance of existing cartilage within joints?

• A. Osteoblasts
• B. Osteoclasts
• C. Chondrocytes
• D. Myocytes

Answer: (C)

Chondrocytes are the specific cell type responsible for the maintenance and health of existing cartilage within joints. These cells are embedded within the cartilage matrix and play a crucial role in synthesizing and maintaining the extracellular matrix components such as collagen and proteoglycans. This matrix is essential for providing the structural support and resilience that cartilage needs to withstand compressive forces within joints. Maintaining cartilage is vital for joint function, as it helps to absorb shock and reduce friction between the articulating surfaces of bones. When chondrocytes are damaged or dysfunctional, it can lead to conditions like osteoarthritis, where the cartilage deteriorates and joint pain increases. The other cell types listed do not have this function; osteoblasts are involved in bone formation, osteoclasts are responsible for bone resorption, and myocytes are muscle cells. Each plays a vital role in their respective tissues, but chondrocytes are unique in their focus on cartilage maintenance.
