What type of connective tissue covers the moving surfaces of the bone?

Articular cartilage is the type of connective tissue that covers the moving surfaces of bones at the joints. This specialized cartilage serves several important functions. It provides a smooth, lubricated surface for joint movement, reducing friction between bony surfaces during movement. Additionally, articular cartilage helps to absorb shock and distribute loads across the joint, which is particularly important during activities that involve weight-bearing, such as walking or running.

The structure of articular cartilage is unique, as it is composed of a mixture of collagen fibers and proteoglycans, which contributes to its strength and resilience. Unlike other types of cartilage, articular cartilage lacks a direct blood supply and has a limited capacity for self-repair, which emphasizes the necessity of its health for joint functioning.

Understanding the role and composition of articular cartilage helps clarify its importance in maintaining joint integrity and function throughout a person's life.
