The classification of joints in the human body is primarily based on their structure and function. The correct classification includes synovial, cartilaginous, and fibrous joints.

Synovial joints are the most common type and are characterized by a fluid-filled joint cavity. This structure allows for a wide range of motion and includes joints such as the knee and hip. They are essential for movement and flexibility.

Cartilaginous joints, on the other hand, are connected by cartilage and allow for limited movement. An example is the joints between the vertebrae of the spine, which provide stability while still allowing some movement.

Fibrous joints are connected by dense connective tissue and typically permit little to no movement, such as the sutures of the skull, which firmly hold the bones together.

This classification system effectively captures the nature and funcionality of joints in the body, making it essential for understanding the mechanics of movement and stability within the musculoskeletal system.
