121

movement in an anterior-posterior (AP) plane that increases the angle between the articulating bones.

extension

122

when a joint is extended more than 180 degrees

circumduction

127

a pivoting motion in which a bone turns on its own longitudinal axis

rotation

128

lateral rotation

?

129

medial rotation

?

130

the medial rotation of the forearm so the that the palm of the hand is directed posteriorly or inferiorly.

pronation

131

occurs when the forearm rotates laterally so that the palm faces anteriorly or superiorly.

supination

132
