What does lateral mean in medical terminology?

The term "lateral" in medical terminology refers to the side of the body that is farther from the midline. In other words, it is the opposite of "medial". Anatomically, the body is divided into two symmetrical sides, left and right, and the lateral aspect is the side that is away from the imaginary dividing line that runs down the center of the body.

For example, if a person is facing forward, their right arm would be considered lateral, while their left arm would be medial. Similarly, the lateral side of the leg is the outer side, away from the midline, while the medial side is the inner side, closer to the midline.

The term "lateral" is used in various medical contexts to describe anatomical structures, pathological conditions, or surgical procedures related to the lateral aspect of the body. It helps healthcare professionals accurately communicate and document medical information related to specific areas or conditions.
