What type of flexible tissue serves as a cushion between bones?

The type of flexible tissue that serves as a cushion between bones is cartilage. Cartilage is a connective tissue that possesses a rubbery and flexible quality, which makes it ideal for absorbing shock and reducing friction in joints. It is found in various parts of the body, including the ends of long bones, the nose, ears, and between vertebrae in the spine.

Cartilage's primary role in joints is to provide a smooth, low-friction surface for bone articulation, while also acting as a shock absorber during movement and weight-bearing activities. This cushioning effect not only helps in protecting the bones from damage but also contributes to overall joint health and function.

In contrast, ligaments connect bones to other bones, providing stability to joints but not serving as a cushion. Tendons attach muscles to bones, facilitating movement but also lacking the cushioning characteristic. Synovial fluid, while crucial for lubrication within joint cavities, is a fluid rather than a tissue, and therefore does not provide the structural cushioning that cartilage does.
