Verified step by step guidance

Begin by understanding the types of synovial joints in the human body. Synovial joints are characterized by a fluid-filled joint cavity that allows for a wide range of motion.

Identify the characteristics of a hinge joint. Hinge joints allow movement primarily in one plane, similar to the opening and closing of a door. This type of joint permits flexion and extension.

Consider the anatomy of the elbow joint. The elbow is formed by the articulation between the humerus, radius, and ulna bones.

Recognize that the elbow joint functions primarily as a hinge joint, allowing for flexion and extension of the forearm relative to the upper arm.

Compare the elbow joint to other types of synovial joints, such as ball and socket joints (e.g., shoulder and hip), saddle joints (e.g., thumb), and pivot joints (e.g., neck), to confirm that the elbow's movement is consistent with a hinge joint.
