The prefix Lobo- is most closely associated with which meaning?

• A. Lip
• B. Section
• C. Tail
• D. Spinal column

Answer: (B)

Lobo- points to a lobe, which is a distinct division of an organ. In anatomy, organs like the brain and lungs are described as having lobes, such as the frontal lobe or the lung lobes, and terms built with lobo- convey that idea of a lobed section rather than a simple surface or a whole organ. That’s why this prefix is most closely tied to the concept of a lobe.

If you were thinking about the other options: lip would be represented by labio- or cheilo-, section would use sect- or segment-, tail isn’t described with lobo- (it would be terms related to caudal or tail-like structures), and the spinal column involves vertebr- or spondyl- rather than lobe-related language. So the best match for lobo- is lobe.
