    CHAPTER II. ANATOMY AND PHYSIOLOGY OF THE MOUTH. THE mouth signifies, in the human subject, the space included be- tween the pahitine arch above, the mylohyoid muscles beneath, the lips in front, the velum palati behind, and the cheeks on either side. The teeth and closed jaws separate the inner portion, or lingual cavity, from the outer, or vestibular space; and while that part of the latter bounded by the cheeks ought properly to bear the appellation buccal, the term buccal cavity is not unfrequently employed with a significa- tion so general as to comprehend the whole oral cavity. In the mouth are the tongue, teeth, and the alveolar ridges invested by the gums: into it are poured the secretion of the parotid, sub- maxillary and sublingual glands, as well as that of the ordinary mucous and of the special lingual follicles; and in it the food is sub- jected to the processes of mastication and insalivation previous to deglutition. It is farther concerned in the prehension of aliment; and besides containing the organs of taste, is employed in articulation, expectora- tion, suction, etc. The parts concurring to constitute the mouth form a very compli- cated piece of mechanism ; through them it has a wide range of sym- pathies, and by them it performs a great variety of functions. The anatomical elements composing these parts consist of Bone- Ligament, Muscle, Gland, Bloodvessel, Nerve, Areolar, and Adipose tissues, and Mucous membrane. These different elements combine together and form the various organs which constitute the mouth. These organs I shall consider in their physiological order: thus combining their anatomy and physiology, studying at the same time both their healthy structure and function.
