What anatomical term describes the side of a structure away from the midline?

• A. Medial
• B. Lateral
• C. Posterior
• D. Superior

Answer: (B)

Lateral describes the side away from the midline. The midline is the imaginary line down the center of the body that splits it into left and right halves. Structures that are farther from that center are described as lateral, while those closer to it are medial. The other terms describe different directions: posterior means toward the back, and superior means higher up. Using lateral helps pinpoint where something sits in relation to the body's center, such as ears being lateral to the eyes or limbs positioned away from the midline.
