Verified step by step guidance

1. Begin by understanding the classification of joints in the human body. Joints can be classified into three main types: fibrous, cartilaginous, and synovial.
2. Fibrous joints are connected by dense connective tissue and are typically immovable, such as the sutures in the skull.
3. Cartilaginous joints are connected entirely by cartilage and allow more movement than fibrous joints but are still limited, such as the joints between vertebrae.
4. Synovial joints are the most common type of joint in the limbs and are characterized by a fluid-filled joint cavity that allows for a wide range of movement. Examples include the knee, elbow, and shoulder joints.
5. Recognize that the limbs require a high degree of mobility, which is provided by synovial joints. Therefore, all joints of the limbs are classified as synovial joints.
