Step 1: Understand the definition of synovial joints. Synovial joints are characterized by the presence of a synovial cavity filled with synovial fluid, which allows for free movement between the articulating bones. Examples include ball-and-socket, hinge, and pivot joints.
Step 2: Review the types of synovial joints mentioned in the problem. Ball-and-socket joints (e.g., shoulder and hip), hinge joints (e.g., elbow and knee), and pivot joints (e.g., the joint between the first and second cervical vertebrae) are all synovial joints.
Step 3: Examine the term 'suture.' Sutures are fibrous joints found in the skull, where bones are tightly bound by dense connective tissue. They do not have a synovial cavity and are immovable, making them non-synovial joints.
Step 4: Compare the characteristics of sutures with synovial joints. Sutures lack the features of synovial joints, such as synovial fluid, a synovial cavity, and free movement.
Step 5: Conclude that 'suture' is not a synovial joint, as it does not meet the criteria for synovial joints, unlike the other options provided in the problem.
