What are synovial joints?
Synovial joints are types of joints that allow for free movement between the bones, characterized by a fluid-filled joint cavity.
What is synovial fluid?
Synovial fluid is a viscous fluid found in the joint cavities, which lubricates the joints and reduces friction during movement.
Examples of synovial joints?
Examples include the knee, elbow, hip, and shoulder joints.
What is the function of articular cartilage in synovial joints?
Articular cartilage covers the ends of bones in synovial joints, providing a smooth surface for movement and absorbing shock.
What are ligaments?
Ligaments are strong connective tissues that connect bones to other bones at a joint.
What is the joint capsule?
The joint capsule is a fibrous envelope that encloses the joint cavity, providing stability and protecting the joint.
What is the role of bursae in synovial joints?
Bursae are small fluid-filled sacs that reduce friction between tissues such as bones, muscles, and tendons.
What is a hinge joint?
A hinge joint is a type of synovial joint that allows for back-and-forth motion, like the elbow and knee.
What is a ball-and-socket joint?
A ball-and-socket joint permits the most movement, including rotation, like the shoulder and hip joints.
