Anchored to the floor of the mouth and slung at the rear from
muscles attached to a spiky outgrowth at the base of the skull, the tongue is a
strong muscle that is covered by the lingual membrane, which has special areas
which detect the flavor of food.
The tongue is made up of muscles covered by
mucous membranes. These muscles are attached to the lower jaw and to the hyoid
bone (a small, U-shaped bone, which lies deep in the muscles at the back of the
tongue) above the larynx.
There are 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.
Babies have many more taste buds than an adult, and they have these almost
everywhere in the mouth, including the cheeks. Nevertheless, adults enjoy more
flavors than babies, who dislike bitter tastes and prefer bland food. The tongue
also aids in the formation of sounds of speech and coordinates its movements to
aid in swallowing. It is especially helpful when we are forced to "eat our
words." Enjoy!
