What is found in freely movable joint cavities?
Synovial membranes
Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee.
What allows joints to move freely?
Structure of a joint Smooth cartilage prevents friction as the bones move against one another. In freely movable joints, the entire joint is enclosed inside a membrane filled with lubricating synovial fluid, which helps to provide extra cushioning against impact.
What does the joint cavity contain?
The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule. This fluid-filled space is the site at which the articulating surfaces of the bones contact each other.
What is a joint cavity?
Synovial joints
Synovial joints are the only joints that have a space between the adjoining bones. This space, referred to as the synovial (or joint) cavity, is filled with synovial fluid. Synovial fluid lubricates the joint, reducing friction between the bones and allowing for greater movement.
What type of fluid is present in joint cavities?
Synovial fluid is present in joint cavities of freely movable joints. Which of the following statements is true about this fluid? A. It contains hydrochloric acid. B. It contains enzymes only. C. It contains hyaluronic acid. D. It contains lactic acid.
What is the articular cavity surrounded by?
The cavity is surrounded by the articular capsule, which is a fibrous connective tissue that is attached to each participating bone just beyond its articulating surface. The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule.
What is the structure of the synovial joint?
Its joint cavity characterizes the synovial joint. The cavity is surrounded by the articular capsule, which is a fibrous connective tissue that is attached to each participating bone just beyond its articulating surface. The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule.
What fluid is secreted from the synovial membrane?
The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule. Hyaline cartilage forms the articular cartilage, covering the entire articulating surface of each bone.
