Understand the types of joints: Joints in the human body are classified into three main categories based on their structure and function: fibrous, cartilaginous, and synovial joints.
Identify characteristics of cartilaginous joints: These joints are connected entirely by cartilage, allowing more movement than fibrous joints but less than synovial joints. They are typically found in areas requiring stability and slight movement.
Examine the options provided: The shoulder joint and elbow joint are synovial joints, which are characterized by a fluid-filled joint cavity that allows for a wide range of motion. Sutures of the skull are fibrous joints, which are immovable and connected by dense connective tissue.
Focus on the pubic symphysis: The pubic symphysis is a cartilaginous joint located between the left and right pubic bones. It is connected by fibrocartilage, allowing slight movement and providing stability to the pelvic region.
Conclude the classification: Based on the characteristics and location, the pubic symphysis is correctly classified as a cartilaginous joint, distinguishing it from the other options provided.
