Final answer:
Cartilaginous joints, allowing very little movement, include two types: synchondroses and symphyses, also known as amphiarthroses.
Step-by-step explanation:
Cartilaginous joints in the body allow for very little movement. These joints are found where the bones are connected by cartilage. There are two types: synchondroses, where bones are joined by hyaline cartilage such as in epiphyseal plates in children's growing bones, and symphyses, where the connection between bones is made through fibrocartilage like at joints between vertebrae. Cartilaginous joints are also known as amphiarthroses because they allow for limited movement compared to freely movable synovial joints.
