What type of cartilage is primarily found in synovial joints?

In synovial joints, the primary type of cartilage present is articular cartilage, which is a specialized form of hyaline cartilage. Articular cartilage covers the ends of the bones at the joint surface, providing a smooth, slippery surface that reduces friction during movement and allows for easy joint motion. This cartilage also serves to absorb shock and distribute loads across the joint, contributing to the overall function and stability of synovial joints.

While hyaline cartilage is a broader category that includes articular cartilage, articular cartilage's specific adaptations—such as its capacity to withstand compressive forces and its smooth surface—make it particularly suited for the dynamic environment of synovial joints. Other forms of cartilage, like elastic and fibrocartilage, have different properties and functions, making them unsuitable for the primary role in the structure and mechanics of synovial joints.
