lip
One of the two fleshy folds which surround the opening of the mouth. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the lip is
One of the two fleshy folds which surround the opening of the mouth. The atlas records it as an anatomical structure at the organ scale in the human body.
Where the lip is
It sits in the head, within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What the lip connects to
The atlas records 13 typed relationships for it, across 8 kinds of connection. part of face and mouth.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the lip. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
Also called
Also recorded as labia oris and lips. Searching any of those names reaches this page.

Questions
Where is the lip?
It sits in the head, within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the lip connect to?
Part of: face and mouth.
Is the lip the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
