tonsil

Either of the two small almond-shaped masses of lymph tissue found on either side of the oropharynx. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the tonsil is

Either of the two small almond-shaped masses of lymph tissue found on either side of the oropharynx. The atlas records it as a lymphatic at the organ scale in the human body.

Where the tonsil is

It sits within the respiratory, digestive and lymphatic & immune systems. 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 tonsil connects to

The atlas records 15 typed relationships for it, across 6 kinds of connection. part of tonsillar ring.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the tonsil. 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.

Questions

Where is the tonsil?

What does the tonsil connect to?

Part of: tonsillar ring.

Is the tonsil 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.
