41
ball and socket joints
one surface spherical and the other cup-shaped allowing movement in all directions like hip and shoulder
42
hinge joint
one surface convex and the other concave allowing them to fit together like a clasp as the elbow and knee
43
Ellipsoid joints
an oval bone projection that fits into a rough elliptical cavity of another bone making movement on two planes possible as the atlas-occipital where the head attaches to the body
