What does lateral mean?

• A. Toward the midline of the body.
• B. Away from the midline of the body.
• C. Toward the upper part.
• D. Toward the back end.

Answer: (B)

Lateral means away from the midline of the body—the imaginary line that divides left from right. So, structures farther from that center line are described as lateral, while those closer to it are medial. For example, the ears are lateral to the eyes, and the arms are lateral to the chest. In contrast, terms like medial (toward the midline), superior (toward the head), or posterior (toward the back) describe other directions.
