When it comes to synonyms for the word, some of the commonly used terms include the lingual muscle, the glossostyloid muscle, and the styloglossal muscle. The lingual muscle is the most widely used synonym since it refers to any muscle that is present in the tongue, while the other terms are more specific and refer to the muscle's origin and course.
