The term "later" is used to indicate what positional aspect in the body?

The term "later" is derived from the anatomical term "lateral," which is used to specify a position that is away from the midline of the body, indicating the side aspect. In anatomical terminology, "lateral" pertains to structures located towards the outer sides of the body or an organ. For instance, the ears are lateral to the eyes.

Understanding directional terms like "lateral" is vital in anatomy and medicine because it helps healthcare professionals accurately communicate the locations of various body parts. Terms like "medial," which refers to being closer to the midline, and "lateral" can often be contrasted to give context to specific locations, such as how a shoulder might be described in relation to the torso. In this case, "later" correctly signifies a positional aspect relative to the sides of the body.
