How is Lateral defined in relation to the body?

Near to the midline
Away from the midline
Towards the front
Towards the back

The correct answer is: Away from the midline

Lateral refers to a position in relation to the midline of the body, specifically indicating a location that is further away from the midline. When using anatomical terms, the midline is an imaginary vertical line that divides the body into equal left and right halves. Therefore, when something is described as lateral, it means that it is situated on the side of the body, or away from this central area. For example, the arms are lateral to the chest, as they are located further from the midline of the body. This terminology is essential for accurately describing the positioning of different body parts in relation to one another.
