palatopharyngeus muscle

The palatopharyngeus or palatopharyngeal or pharyngopalatinus muscle is a long, fleshy fasciculus, narrower in the middle than at either end, forming, with the mucous membrane covering its surface, the palatopharyngeal arch. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the palatopharyngeus muscle is

The palatopharyngeus or palatopharyngeal or pharyngopalatinus muscle is a long, fleshy fasciculus, narrower in the middle than at either end, forming, with the mucous membrane covering its surface, the palatopharyngeal arch. The atlas records it as a muscle at the organ scale in the human body.

Where the palatopharyngeus muscle is

It sits in the head, within the muscular, respiratory and digestive 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 palatopharyngeus muscle connects to

The atlas records 13 typed relationships for it, across 6 kinds of connection. part of chordate pharynx, material anatomical entity and respiratory system.

Supply and innervation

Innervation: accessory XI nerve and vagus nerve.

Questions

Where is the palatopharyngeus muscle?

It sits in the head, within the muscular, respiratory and digestive 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 does the palatopharyngeus muscle connect to?

Part of: chordate pharynx, material anatomical entity and respiratory system.

Is the palatopharyngeus muscle 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.
