Obj. 18
Ball and socket synovial joints
are fairly stable.
The more ligament a joint has,
the more stable.
A ligament can stretch 6% of its
length before it snaps.
Tone of muscles that cross a
joint contributes to joint strength
Name two places in your
body you have synovial
joints?
What tissue gives

strength?
