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. Anatomical Axis: Axis are used to describe

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
