Understand the definition of a synovial joint: Synovial joints are characterized by a fluid-filled joint cavity that allows for a wide range of motion. They are the most common and movable type of joint in the body.
Identify the types of synovial joints: Common types include hinge joints (like the elbow), ball-and-socket joints (like the shoulder), pivot joints (like the neck), and saddle joints (like the thumb).
Examine the characteristics of a suture joint: Suture joints are fibrous joints found in the skull. They are immovable and do not have a joint cavity, which distinguishes them from synovial joints.
Compare the characteristics: Synovial joints have a joint cavity and allow for movement, whereas suture joints are immovable and lack a joint cavity.
Conclude which joint is not synovial: Based on the characteristics, the suture joint does not fit the definition of a synovial joint, as it is immovable and lacks a joint cavity.
