    1. Movement in Planes and Axis of Rotation

    2. A body movement can be described in terms of the anatomical plane through which it occurs and the anatomical axis around which it rotates. The GENERAL RULE: The axis of rotation is perpendicular to the plane of movement. Describing Position and Movement

    3. Anatomical Axis: Axis are used to describe how rotation of the muscles and bones take place. Longitudinal or polar axis: is in a north-south relationship to the anatomical position. Horizontal or bilateral axis: is in an east-west relationship to the anatomical position. Antero-posterior axis: is in a front-to-back relationship to the anatomical position. Anatomical Axis

    4. Movements on Axis

    5. Anatomical Planes: Anatomical planes relate to positions in space and are at the right angles to one another. Transverse (horizontal) plane: divides the body into superior and inferior segments. Sagittal plane: divides the body in medial and lateral segments. Frontal or coronal plane: divides the body into anterior and posterior segments. Anatomical Planes
