What is the connective tissue that cushions joints?

The connective tissue that cushions joints is cartilage. Cartilage is a flexible tissue that provides support and reduces friction between bones at joints, acting as a shock absorber during movement. It has a smooth surface that allows bones to glide over one another effectively, which is crucial for maintaining joint function and health. The unique properties of cartilage, including its ability to withstand compressive forces and its relative resilience, make it essential for preventing wear and tear on the bones, thereby playing a vital role in overall musculoskeletal health. This is specifically true for types of cartilage such as hyaline cartilage, which is found on the surfaces of joints, and fibrocartilage, which is present in areas such as the knee and intervertebral discs.
