Document Summary

Language is important when talking about orientation and how the body moves. To the right is the anatomical position. All movement is described from this starting point. These terms are in reference to the anatomical position: proximal (closer to origin) vs. distal (away from origin, medial (closer to midline) vs. lateral, superior (towards head) vs. Plane: a flat surface that divides the body or a segment. Axis: a pin of axle about which the body or segment rotates. There are three different axes that the body will rotate around. Example: when throwing a baseball, the trunk rotates about the longitudinal axis while the arms rotate about the mediolateral axis. From each plane, there are six basic movements: flexion (closing the joint angle) and extension (opening the joint angle, abduction (take away from the body) and adduction (add to the body) o. Internal and external rotation (rotation around a segment)
