The sagittal plane of the human body is an imaginary slice made from the top of the head down, cutting the body into two more or less mirror-image halves. It runs from the nose to the back of the head, unlike the coronal plane, which runs from ear to ear. See the diagram of anatomical positions.

Differences between the two halves are found primarily in the heart and other internal organs, but subtle differences can also be seen in the two halves of the human face. Try holding a pocket mirror with its edge against the center of your own photo, showing one side reflected to make a whole face.
