In neuroanatomy, distal relative to the midline means nuclei are which of the following?

• A. Closer to the midline
• B. Farther from the midline
• C. Anterior to the midline
• D. Posterior to the midline

Answer: (B)

The idea being tested is how to interpret distance from the brain’s midline. The midline is the central plane that divides left and right. Structures close to that line are medial; those farther away are lateral. So when something is described as distal relative to the midline, it means it is farther from the midline, i.e., more lateral. That’s why the correct choice is “farther from the midline.” The other options refer to front/back positions (anterior/posterior) or to being close to the midline (medial), not to distance from the midline.
