Lobe (anatomy)

In anatomy, a lobe is a clear anatomical division or extension [eMedicineDictionary|lobe] [Dorlands|l_13|12500046] 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. [ [http://www.siumed.edu/~dking2/intro/glands.htm#5 SIU SOM Histology GI ] ]

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. [Dorlands|l_13|12500626]
