Which joint classification allows for slight movement?

The classification that allows for slight movement is amphiarthrotic joints. These joints provide a balance between stability and mobility, facilitating limited movement between the connected bones. They are typically found in areas of the body where some flexibility is beneficial, such as in the joints of the spine where the vertebrae are connected by intervertebral discs, or in the pubic symphysis.

In contrast, diarthrotic joints are characterized by free movement and are commonly found in areas like the knee or shoulder. Synarthrotic joints, on the other hand, are immovable joints such as those found in the skull, where bones are tightly fused together. Hinge joints, while allowing movement in one plane (like the elbow and knee), do not pertain specifically to joint classification based on the degree of movement they allow. Thus, amphiarthrotic joints specifically denote those that permit slight movement, making this classification the correct choice.
