What is the functions of the muscles in tongue and jaw?

The muscles of the tongue are primarily responsible for its movements, enabling functions such as speaking, swallowing, and tasting. They allow for intricate positioning and manipulation of food during chewing and aid in the formation of speech sounds. The jaw muscles, particularly the masseter and temporalis, facilitate the opening and closing of the mouth, enabling chewing and grinding of food. Together, these muscle groups coordinate the processes of mastication and articulation.
