Hyoglossus

Fibers arising from the the lesser cornu of the hyoid bone and inserting on the dorsum of the tongue are frequently separate from the hyoglossus and have been named chondroglossus.

The fibers arising from the body of the hyoid are frequently separated by a distinct interval from those arising from the greater cornu, the former constituting the basioglossus and the latter, the ceratoglossus.

A bundle of fibers, forming triticeoglossus, arise from the cartilago triticea, passing proximally and forward to insert along with the posterior fibers of the hyoglossus. Geniohyoid, which may be doubled bilaterally, may originate from hyoglossus fibers.
