    ease be permanent, it may be cured by complete division of the muscle, unless the operation be contra-indicated from other causes. Finally, the neck is naturally divided into three regions,—the anterior, supra-clavicular or lateral, and the posterior. SECTION FIRST. ANTERIOR PORTION. The anterior portion of the neck comprehends the collection of organs placed anterior to the cervical portion of the spine. We here see the supra-sternal fossa, the laryngeal, and sterno- mastoid eminences. The supra-sternal fossa extends to the parotid region, thus forming on each side a groove, which, large and deep superiorly, is superficial and indistinct in the middle, taking the name of thyro-mastoid groove. Between the larynx and the maxilla, is observed the thyro-maxillary groove, placed transversely, lying upon the os hyoides. These various objects subdivide the anterior of the neck into two secondary regions; one superior submaxillary, or supra-hyoid, may also be called sublingual; the other, inferior and less, the sub-hyoid. Supra-hyoid region.—Limited above by the base of the jaw and floor of the mouth, laterally by the anterior border of the sterno-mastoid muscle, larger in the middle; this is, moreover, continuous with the parotid region. The oblique plane which it forms, from above downwards, rising and falling with the motions of the tongue, is transformed, in some individuals, into a decided projection, or semilunar prominence, separated from the jaw by a fissure. This constitutes double chin. Fine, thin, very elastic in children and females, thicker in man, on account of the beard, the ski?i frequently presents trans- verse furrows, which always remain, notwithstanding the posi- tion of the head, depending upon the action of the platisma muscle, perhaps, as much as upon the motions of the jaw. The follicles are larger here than in the other regions of the neck, but less than in the face; consequently, pustular affections are very common. The subcutaneous tissue consists of three layers. Formed of cellulo-filamentous tissue, containing adipose vesicles, ordinarily very minute, but capable of increasing to a considerable extent ; thus constituting that submental projection already mentioned. The first unites the skin to the platisma muscle, so firmly that, in contracting, it draws the integuments with it. The second con- sists of the platisma muscles, which, on the median line, leave a small triangular space between them, having its base down- wards. The third, formed of cellulo-lamellous tissue, united very loosely to the cervical fascia, upon which it moves, adheres H
