This mobility is largely due to the extensive intrinsic musculature. The tongue is developed from the tuberculum impar, which furnishes the larger anterior part (fig. 221), the rest arising from the fleshy ridges above the hyoid arch. In the adult the line between these parts is largely obliterated, but it lies near the line of circumvallate papillae
