Which term describes a point away from the midline of the body?

The term that describes a point away from the midline of the body is "lateral." In anatomical terminology, "lateral" refers to structures that are situated on the outer sides of the body or farther from the midline, which is an imaginary line that divides the body into equal right and left halves.

For example, if you consider the arms in relation to the torso, the arms are lateral to the midline of the body. This term is frequently used in medical contexts to provide clarity regarding the location of body parts, ensuring precise communication about anatomy and medical conditions.

In contrast, "medial" describes a point towards the midline, "proximal" refers to a position closer to the point of attachment or origin (often used with limbs), and "posterior" indicates a position towards the back. Each of these terms serves a specific purpose in describing anatomical locations, but in this case, "lateral" is the correct choice for denoting a position away from the midline.
