9.3 Cartilaginous Joints

Epiphyseal Cartilages

are actually hyaline cartilage growth centers during endochondral bone formation, not joints associated with movements.

Synchondrosis

is a cartilaginous joint in which the connecting material is hyaline cartilage and is slightly movable (amphiarthrosis) to immovable (synarthrosis).

Symphyses

is a cartilaginous joint in which the ends of the articulating bones are covered with hyaline cartilage, but a broad, flat disc of fibrocartilage connects the bones. All symphyses occur in the midline of the body.

cartilaginous joints

lacks a synovial cavity and allows little or no movement. Here the articulating bones are tightly connected by either hyaline cartilage or fibrocartilage.

The pubic symphysis between the anterior surfaces of the hip bones is one example of a ___________________. This type of joint is also found at the junction of the __________________________ and at the intervertebral joints between the bodies of vertebrae . A portion of the intervertebral disc is composed of ___________________. A symphysis is a slightly movable joint (amphiarthrosis).
