What does lateral refer to in anatomical terms?

In anatomical terminology, "lateral" specifically refers to structures that are situated away from the midline of the body. Understanding the midline concept is essential, as it serves as a reference point for describing the position of various body parts. When something is described as lateral, it means that it is located towards the sides of the body, indicating a position that is further from the center or median plane than another structure.

For example, the human arms are lateral to the torso. This term is frequently used in anatomy to give a precise description of locations and relationships between different parts of the body, ensuring clear communication in medical contexts. In contrast, the other terms provided do not align with the definition of lateral; they refer to different positions or orientations relative to the body’s midline.
