What term is used to describe a position "toward the side of the body, away from the midline"?

The term that describes a position "toward the side of the body, away from the midline" is lateral. This anatomical term is used to indicate the relative position of structures in relation to the midline of the body. When something is described as lateral, it means it is situated on the outer side of the body or farther from the center line that divides the body into left and right halves.

For clarity, medial would refer to something that is closer to the midline rather than away from it. Proximal and distal are terms that relate to the location of structures in relation to a point of attachment or reference point, commonly used for limbs. Proximal means closer to the point of attachment, while distal means farther away from it. Therefore, lateral specifically addresses the position away from the midline, making it the correct choice in this context.
