Final answer:
The muscles ending in the suffix -glossus, meaning 'tongue', and controlling tongue movement are the genioglossus, styloglossus, palatoglossus, and hyoglossus. These extrinsic muscles originate from various parts of the skeletal structure and insert into the tongue, enabling complex motions necessary for functions like speech and swallowing.
Step-by-step explanation:
Muscles that end in the suffix -glossus, meaning 'tongue', are part of the group of extrinsic tongue muscles that control various movements of the tongue. These include the genioglossus muscle which originates on the mandible and moves the tongue downward and forward, the styloglossus which originates on the styloid bone and moves the tongue upward and backward, the palatoglossus that originates on the soft palate and elevates the back of the tongue, and the hyoglossus which originates on the hyoid bone and moves the tongue downward and flattens it. In addition, the mylohyoid muscle, part of this group, is responsible for raising the tongue, complementing the individual actions of the other muscles and contributing to the tongue's essential roles in chewing, swallowing, and speaking.
