Final answer:
A cartilaginous joint is a joint where the adjacent bones are united by either hyaline cartilage or fibrocartilage. The amphiarthrotic joint with a wedge or pad of fibrocartilage is a type of cartilaginous joint called a symphysis.
Step-by-step explanation:
A cartilaginous joint is a joint where the adjacent bones are united by cartilage. There are two types of cartilaginous joints: synchondrosis and symphysis. In a synchondrosis joint, the bones are connected by hyaline cartilage, while in a symphysis joint, the bones are connected by fibrocartilage. The amphiarthrotic joint where bones are separated by a wedge or pad of fibrocartilage is a type of cartilaginous joint, specifically a symphysis joint.
