Anatomical terms and planes help to describe locations of body structures and movements. Understanding the anatomical planes enables you to correctly orientate prosections and scans (e.g. CT).
An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and non-human anatomy, three principal planes are used: The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture.
The planes of the body are anatomical concepts often used by health professionals to describe how your body moves during exercise or other activities. You can visualize them as flat surfaces...
An anatomical plane is just a slice through the body. This slice however can be done at different angles with respect to the body. The three most commonly used planes are: sagittal, coronal and transverse. The sagittal plane divides the body into left and right regions.
Body planes are used to describe anatomical motion in the X-Y-Z coordinate system that the body moves through. An anatomist could model a limb’s range of motion by measuring which planes the limb can move through and how far it is able to travel.
Understanding anatomical directional terms and body planes will make it easier to study anatomy. It will help you to be able to visualize positional and spatial locations of structures and navigate directionally from one area to another.
When used in conjunction with anatomy, planes are used to divide the body and its parts, which allows you to describe the views from which you study the body. If you look at your A&P textbook, you’ll most likely notice that a good number of the pictures and diagrams make use of planes.
