Features of Synovial Joints
Articular cartilage covers the ends of bones
A fibrous articular capsule encloses joint surfaces
A joint cavity is filled with
Ligaments

Developmental Aspects of the Skeletal System
At birth, the skull bones are incomplete
Bones are joined by fibrous membranes
Fontanels are completely replaced with bone
