What are the three types of joints?

The three types of joints classified in human anatomy are immovable, slightly movable, and freely movable, making this choice the most accurate.

Immovable joints, known as synarthroses, do not allow any movement and provide stability, as seen in the sutures of the skull. Slightly movable joints, or amphiarthroses, permit limited movement, which is typical in joints like the intervertebral discs in the spine. Lastly, freely movable joints, referred to as diarthroses, allow a wide range of motion and are exemplified by the elbow and knee joints.

This classification effectively captures the functional characteristics of joints in the body, thereby aiding in the understanding of how they contribute to movement and stability.
