Question

Quizplus · Accepted Answer

The genioglossus is the primary muscle responsible for protruding and retracting the tongue, as well as contributing to its medial deviation. Sticking the tongue out involves protrusion, so the little girl most likely used her genioglossus muscle to stick her tongue out at you. The orbicularis oris is responsible for pursing and puckering the lips, while the stylohyoid and hyoglossus muscles are involved in tongue movement but not specifically protrusion.
