The palatoglossus is the only muscle of the tongue that is not innervated by the hypoglossal nerve (CN XII). It is innervated by the Vagus nerve (CN X)

But some sources state that the palatoglossus is innervated by fibres from the cranial part of the accessory nerve (CN XI) that travel via the pharyngeal plexus.[1]

Other sources state that the palatoglossus is not innervated by XI hitchhiking on X, but rather it is innervated by X via the pharyngeal plexus formed from IX and X.[2]
