Verified step by step guidance

Step 1: Begin by understanding what synovial joints are. Synovial joints are a type of joint in the human body that allow for a wide range of motion. They are characterized by the presence of a synovial cavity filled with synovial fluid, which reduces friction and facilitates movement.

Step 2: Review the six main categories of synovial joints. These include hinge joints, ball-and-socket joints, pivot joints, saddle joints, condyloid joints, and plane joints. Each type is classified based on the shape of the articulating surfaces and the type of movement they allow.

Step 3: Analyze the options provided in the question. The options include: (1) the shape of their articulating surfaces, (2) the number of bones involved, (3) the presence of cartilage, and (4) the amount of synovial fluid produced. Consider which of these factors directly relates to the classification of synovial joints.

Step 4: Recall that the classification of synovial joints is based on the shape of their articulating surfaces, as this determines the type and range of motion the joint can perform. For example, a ball-and-socket joint allows for rotational movement, while a hinge joint permits flexion and extension.

Step 5: Eliminate the other options. The number of bones involved, presence of cartilage, and amount of synovial fluid produced are important features of synovial joints but do not determine their classification. Focus on the shape of the articulating surfaces as the correct basis for classification.
