*Abduction: Pendular movement away from the median plane
*Abduction: Pendular movement away from the median plane
*Circumduction: Combination of flexion and extension that allows a limb to create a circular movement

==Types of Joints==
*Plane Joint: describes translational movement; in reality, nonexistent, as all articular surfaces are curved
*Hinge Joint: movement allowed in one plane only, inhibited by collateral ligaments and/or bony protuberances (eg. elbow joint)
*Pivot Joint: comprises a peg fitted with a ring, movement occurs about the long axis of the peg (eg. radioulnar joint)
*Condylar Joint: knuckle-shaped condyles vary in distance from one another allowing uniaxial movement with limited rotation (eg.femorotibial joint)
*Ellipsoidal Joint: ovoid convex articulation allows movement in two planes at right angles with limited rotation (eg. radiocarpal joint)
*Saddle Joint: also biaxial with a greater scope for rotation
*Spheroidal Joint: (aka ball-and-socket) multiaxial movement allows for rotational movement in several planes (eg hip joint)
