Adduction
Movement toward the midline of the body
Articulate cartilage
Hyaline cartilage attached to articular bone surfaces
Articulation
Action in which the parts come together at a joint
Ball-and-socket joint
An articulation (as the hip joint) in which the rounded head of one bone fits into a cup like cavity of the other and admits movement in any direction
Dorsiflexion

Goniometer
Instrument for measuring angles (as of a joint of the skull)
Hinge joint
Joint between bones (as at the elbow or the knee) that permits motion in only one plane

Joint
Point of contact between elements of an animal skeleton whether movable or rigidly fixed together with the surrounding and supporting parts (as membranes, tendons, or ligaments)
Ligament
Dense regular connective tissue that attaches bone to bone
Plantar flexion
Bending the foot in the direction of the plantar surface (sole)
Range of motion
Range through which a joint can be moved
Rotation
Moving a bone around its own axis, with no other movement
Synovial cavity
Space between the articulating bones of a synovial joint, filled with synovial fluid. Also called a joint cavity
