Verified step by step guidance

Understand the anatomy of the vertebral column: The vertebrae are connected by intervertebral discs, which are composed of fibrocartilage and act as cushions between the bones.

Review the classification of joints: Joints are categorized into three main types based on their structure and function—fibrous, cartilaginous, and synovial.

Focus on cartilaginous joints: These joints are characterized by the presence of cartilage between the bones, allowing limited movement. Intervertebral discs are a prime example of this type of joint.

Eliminate incorrect options: Ball-and-socket joints (e.g., shoulder and hip) allow a wide range of motion, which is not applicable to the vertebrae. Fibrous joints (e.g., sutures in the skull) are immovable, and synovial joints (e.g., knee and elbow) have a fluid-filled cavity for greater mobility, which does not describe the L2-L3 joint.

Conclude that the joint between the L2 and L3 vertebrae is a cartilaginous joint, as it involves fibrocartilage intervertebral discs providing limited movement and support.
