Transcript text: Which key feature distinguishes a synovial joint from other joint types?
- presence of cartilage
- presence of connective tissue
- presence of a joint cavity
- presence of collagen fibers
Solution
The answer is the third one: presence of a joint cavity.
Explanation for each option:
Presence of cartilage: While cartilage is present in synovial joints, it is not unique to them. Cartilage is also found in other types of joints, such as cartilaginous joints.
Presence of connective tissue: Connective tissue is a broad category that includes many types of tissues found throughout the body, including in all types of joints. Therefore, it is not a distinguishing feature of synovial joints.
Presence of a joint cavity: This is the correct answer. Synovial joints are unique in having a joint cavity, which is a space between the articulating bones filled with synovial fluid. This feature allows for a greater range of motion compared to other joint types.
Presence of collagen fibers: Collagen fibers are a component of many tissues, including cartilage and connective tissues, and are not exclusive to synovial joints.
In summary, the presence of a joint cavity is the key feature that distinguishes synovial joints from other types of joints.
