Please note that the content of this book primarily consists of articles

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.
