The anatomical planes are different lines used to dissect the human body. They are particularly prevalent in terminology describing anatomical models and prosections. Using anatomical planes allows the reader to orientate themselves, and gain a good spacial awareness of the structures they are visualising.
There are three planes commonly used – sagittal, coronal and transverse.
The Sagittal Plane - a vertical line, divides the body into a left and right.
The Coronal Plane - a vertical line, divides the body into a front and back
The Transverse Plane - a horizontal line, divides the body into a top and bottom
