What does lobation mean?
Lobation is the formation or condition of lobes, meaning naturally or functionally distinct parts of an organ or other structure. In medicine and anatomy, it describes the way a larger structure is divided into lobes: for example, the liver has hepatic lobation, while the kidney has renal lobation. The word can also refer to an individual projection that resembles a lobe. Lobation is more precise than simply saying that something is rounded or segmented, because it emphasizes the organized division of a structure into functional or anatomical regions. Although related terms such as lobe, lobule, and lobular are more familiar, lobation remains useful in technical description, especially in anatomy, diagnostic imaging, biology, and the study of physical forms. Its specialized character means that it is not normally used for ordinary descriptions of vaguely rounded or uneven surfaces.
nounThe formation or condition of having lobes, especially the division of an organ into distinct lobed regions. It can also refer to a lobed projection or structure.
- The formation, condition, or arrangement of lobes.
- A lobed or projecting part.
"The lobation of the liver allows it to perform several distinct metabolic functions."
"Imaging revealed abnormal lobation in the upper lobe of the right lung."
"The natural lobation of the kidney is most clearly visible in cross-sectional scans."
The plural is grammatically possible but is rarely needed because the word normally appears in technical descriptions of individual structures.
"The differing lobations of the lungs reflect their separate anatomical organization."
Lobation is anatomy's name for the art of dividing an organ into distinctive lobes.

Where does lobation come from?
Lobation was formed from the English word lobe with the suffix -ation, indicating a process, condition, or resulting structure. Lobe itself comes through French from Latin lobus, meaning “lobe” or “division of an organ.” The same Latin root produced related English forms such as lobule, lobular, and lobectomy.

How lobation is actually used
This is a specialized term used chiefly in anatomy, medicine, biology, and descriptive morphology. It is less common in general usage than the related terms lobe and lobular.
Easily confused with lobation
Lobation refers more generally to the presence or formation of lobes, whereas lobulation specifically describes subdivision into small lobules.
