Verified step by step guidance

Step 1: Understand the classification of joints based on their structure and the type of connective tissue that holds them together. Joints are categorized into fibrous, cartilaginous, and synovial types.
Step 2: Recall that cartilaginous joints are held together by cartilage, which can be either hyaline cartilage or fibrocartilage. These joints allow limited movement and are found in areas like the intervertebral discs and the pubic symphysis.
Step 3: Differentiate between the other types of joints mentioned in the problem. Fibrous joints are held together by dense connective tissue and allow little to no movement (e.g., sutures in the skull). Synovial joints are characterized by a fluid-filled cavity and allow free movement (e.g., the knee joint). Bony joints occur when two bones fuse together, forming a rigid structure (e.g., the epiphyseal line in mature bones).
Step 4: Focus on the key term 'fibrocartilage' in the problem. Fibrocartilage is a type of cartilage found in cartilaginous joints, specifically in structures like the intervertebral discs and pubic symphysis.
Step 5: Based on the structural classification and the presence of fibrocartilage, conclude that the joint described in the problem is a cartilaginous joint.
