palatoglossus muscle

The palatoglossus, glossopalatinus, or palatoglossal muscle is a small fleshy fasciculus, narrower in the middle than at either end, forming, with the mucous membrane covering its surface, the glossopalatine arch. It arises from the anterior surface of the soft palate, where it is continuous with the muscle of the opposite side, and passing downward, forward, and lateralward in front of the palatine tonsil, is inserted into the side of the tongue, some of its fibers spreading over the dorsum, and others passing deeply into the substance of the organ to intermingle with the Transversus linguæ.

Questions

Where is the palatoglossus muscle?

It sits in the head, within the muscular and digestive systems. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the palatoglossus muscle connect to?

A kind of: palatal muscle and tongue muscle.

Is the palatoglossus 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.
