The main types of joints are fibrous, cartilaginous, and synovial joints.

Front

What is a synovial joint?

Back

A synovial joint is a type of joint that is characterized by a fluid-filled joint cavity, allowing for a wide range of motion.

Front

Front

What are amphiarthroses?

Back

Amphiarthroses are joints that are slightly movable, such as the joints between the vertebrae.

Front

How are joints classified functionally?

Back

Joints are classified functionally as synarthroses (immovable), amphiarthroses (slightly movable), and diarthroses (freely movable).

Front

What is the coronal suture?

Back

The coronal suture is the fibrous joint located between the frontal and parietal bones of the skull.
