What is the term for joints that are slightly movable, often connected by cartilage?

1. Synarthroses

2. Diarthroses

3. Amphiarthroses

4. Fibrous joints

The correct answer is: Amphiarthroses

The term for joints that are slightly movable and often connected by cartilage is known as amphiarthroses. These joints provide a balance between stability and movement, allowing for limited motion while still maintaining the integrity of the skeletal structure. An example of amphiarthroses can be seen in the symphysis pubis, where the two pubic bones are joined by cartilage, enabling slight movement that can accommodate various activities. In contrast, the other types of joints mentioned have different characteristics. Synarthroses are classified as immovable joints, where bones are typically fused together, allowing no movement. Diarthroses, also known as synovial joints, are freely movable joints that allow a wide range of motion, such as the knees and elbows. Fibrous joints are connections between bones that are held closely together by fibrous connective tissue, and these can be either immovable or slightly movable, but they do not specifically refer to the slight mobility associated with amphiarthroses.
