1. BONE
BONY
(a) Serves as site of attachment for the
skeletal muscles.
(b) Serves as lever of motion.
2. ARTICULAR

synovial articulation.
c. Multi-Axial Synovial Joints. In multi-axial joints, motion is possible in all
three planes of space.
(1) The ball-and-socket-type synovial joint has the freest motion in all
directions. A spherically rounded head (ball-like) fits into a receiving concavity (socket).
The hip joint is an example of the ball-and-socket type, with the spherical head of the
femur fitting into the cup or socket (acetabulum) of the pelvic bone.
