sp2606 [1]

Answer:

<u>Cartilagenous joint</u>

Explanation:

A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis. Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. This gives symphyses the ability to strongly unite the adjacent bones, but can still allow for limited movement to occur.
