What does the term "lateral" refer to?

The term "lateral" refers specifically to the side of the body or a structure, contrasting with terms that indicate medial (toward the midline) or superior/inferior (above or below). In medical terminology, "lateral" is often used to describe positions or movements away from the body's midline or from a designated point of reference. For example, when a doctor notes that an injury is located on the lateral aspect of the knee, they are indicating that it is on the outer side of the knee, away from the center of the body. This understanding is essential in anatomy and clinical settings, as it helps in accurately describing locations and guiding treatment.
