When describing injuries, equipment, PPE, clothing, and other items related to the anatomy of the human body, it is important to have a universal language to describe the placement or order of these items. This is especially true when words are the only way to describe a situation, as is the case with written reports or in a deposition. Any explanation where pictures or diagrams cannot be examined readily is a primary reason for having these orienting and directional terms at the ready in your vocabulary.
