What is the term for slightly movable joints?

The term for slightly movable joints is amphiarthrosis. This classification of joints allows for some movement while providing stability and strength. Examples of amphiarthroses include the joints between the vertebrae in the spine and the joint between the pubic bones.

In contrast, synarthrosis refers to joints that are immovable, such as the sutures of the skull. Syndesmosis is a specific type of fibrous joint where two bones are connected by a ligament, permitting very limited movement, which is less than what is seen in amphiarthroses. Diarthrosis corresponds to freely movable joints, such as the shoulders and knees, which enable a wide range of motion. Understanding these distinctions helps clarify how joint classifications impact movement and stability in the body.
