Full Tongue Description
[Continued from above] . . . very small nodules, called papillae, from the top surface of the tongue, which give it its rough texture. Between the papillae at the sides and base of the tongue are small, bulblike structures that are sensory organs, called taste buds, which enable us to enjoy the sensations of flavor and warn us when food is unfit to eat. The muscle fibers are heavily supplied with nerves, so it can manipulate food in the mouth and place it between the teeth for chewing-without being bitten in the process. The tongue also aids in the formation of sounds of speech and coordinates its movements to aid in swallowing.
