    I* The Tongue connects them u> each other, and. passing posteriorly upon the soft palate, extends from the basis to tne apex of the uvula, into which it is inserted. By the action of this muscle, the length of the uvula can he very much diminished; and when its contraction ceases, that body is elongated. The pendulous part of the uvula can also be moved, in certain cases, to either side. It is commonly supposed, that the principal use of this little organ is to modulate the voice ; but there are good reasons for believing, that it has another object. It was remarked by Fallopius, (and the ob- servation has been confirmed by many surgeons since his time,) that the uvula may be removed completely without occasioning any alteration of the voice, or any difficulty of deglutition, if the soft palate be left entire. The soft palate is so flexible, that it yields to the actions of the levatores palati, which draw it up so as to close the posterior nares completely It also yields to the circumflexi or tensores, which stretch it so as to do away its arched appearance. It is therefore very properly called the Palatum MoUe. It is also frequently called the Velum Pen- dulum palati, from the position which it assumes. The Tongue, Which is a very important part of this structure, i, retained m its position and connected with the naU adjoining it, by the following arrangements Ineos hyoides, which a. its name imports re sembles the Greek letter , or half an oval, is sit«aL ed rather below the angles of the lower jaw, in the middle of he upper part of the neck. It is .etained in its posmon by the sterno-hyoidei muscles w d connect it to the upper part of the sternum ; by he coraco-hyoidei, which pass to it obliquely from the
