Why is the tongue muscle not connected at both ends?

The tongue muscle, primarily composed of intrinsic and extrinsic muscles, is not connected at both ends to allow for greater flexibility and mobility. This design enables the tongue to perform a wide range of movements necessary for essential functions such as speaking, swallowing, and tasting. Additionally, the lack of rigid connections at both ends allows for the adaptation of the tongue shape and position, facilitating its role in the oral cavity.
