This question is about anatomy rather than trigonometry. As your Pearson Trigonometry tutor, I focus on helping with trigonometry and related mathematical topics.
If you have any trigonometry problems or questions, feel free to ask, and I'll be happy to guide you through them step-by-step.

주요 개념
질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Synovial Joint Structure
Synovial joints are characterized by a fluid-filled joint cavity that allows free movement between bones. Key components include articular cartilage, synovial membrane, and joint capsule, all working together to facilitate smooth motion and reduce friction.

Example 1
Articular Cartilage
Articular cartilage is a smooth, white tissue covering the ends of bones in synovial joints. It prevents direct bone-to-bone contact by providing a cushioning surface that absorbs shock and reduces friction during movement.

Synovial Fluid
Synovial fluid is a viscous liquid secreted by the synovial membrane within the joint cavity. It lubricates the joint, nourishes the articular cartilage, and further minimizes friction between the bony surfaces during joint movement.
