lobule n : a small lobe or subdivision of a lobe
- A small lobe; a subdivision of a lobe.
In anatomy, a lobe is a clear anatomical division or extension that can be determined without the use of a microscope (at the gross anatomy level.) This is in contrast to a lobule, which is a clear division only visible histologically.
In practice, this division can be somewhat subjective. For example, it can be difficult to precisely distinguish between a interlobar duct and a interlobular duct.
Furthermore, the distinction is not universally accepted, and some sources simply consider a lobule to be a small lobe.
Examples of lobes/lobules

- The three lobes of the human cerebellum
- the earlobe
