Welcome to the MedLibrary.org Wikipedia Supplement on Lobe (anatomy) -- Please Click to Return to Front Page

In anatomy, a lobe is a clear anatomical division or extension¹ 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.²

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.
