You’ll start with a fascinating fact about how we’re born with 270 bones, but grow into adults with 206 bones. We’ll explore what joints are and why they are designed differently. We will learn about fixed fibrous joints of the skull, then slightly movable cartilaginous joints, and finally about the freely movable synovial joints that power running, dancing, and sports.
