The structure permits movements in different planes; rotation is not possible.

Structures allow for sliding back and forth and twisting movements.

This structure permits movement in only one place.

Movement is limited to rotations around a central axis.

The structure permits many movements and bones fit complimentary on the surface of other bones.

Ball-and-socket joint

Condyloid joint

Gliding joint

Hinge joint

Pivot joint

Saddle joint

Ball-and-socket joints consist of bones with a globular head that articulates with a cup-shaped cavity of another bone.

The condyloid joint is an oval-shaped condyle of one bone that fits into the elliptical cavity of another bone.

Gliding joints are articulating surfaces that are not curved.

Hinge joints fit into the concave surface of another bone.

Pivot joints are the cylindrical surface of one bone that rotates within a ring formed of bones and fibrous tissues of a ligament.

Saddle joints are formed between bones whose articulating surfaces only have concave regions.
