The pharynx is the part of the food canal that is crossed by the passageway for the air. To keep the food from passing out of its natural channel, the openings into the air passages have to be carefully guarded. This is accomplished through the soft palate and epiglottis, which are operated somewhat as valves.
There is one circumstance of not unfrequent occurrence, which will at once decide the case the presence of indigestible matter, probably small in quantity, in the back part of the mouth. This speaks volumes as to the depraved appetite of the patient, and the loss of power in the muscles of the pharynx. Little will depend on the tonsils of the throat.
In the former case, the worm inserts the stretched out and attenuated anterior extremity of its body into any little crevice, or hole; and then, as Perrier remarks, the pharynx is pushed forwards into this part, which consequently swells and pushes away the earth on all sides. The anterior extremity thus serves as a wedge.
Inflammation of the pharynx and larynx may persist for several weeks unless properly treated. Abscesses may form in the region of the throat. Horses frequently become thick winded as a result of severe attacks of sore throat. The treatment is both preventive and curative. "Colds" and sore throat can be largely prevented by good care, exercise and properly ventilated stables.
The razor had passed through the glosso-epiglottidean fold, a tip of the epiglottis, and through the pharynx down to the spinal column. There was little hemorrhage, but the man could neither swallow nor speak. The wound was sutured, tracheotomy done, and the head kept fixed on the chest by a copper splint.
In another case the contents of the pharynx were not acid, those of the gizzard doubtfully so, while those of the intestine were distinctly acid at a distance of 5 cm. below the gizzard. Even with the higher herbivorous and omnivorous animals, the contents of the large intestine are acid.
The organs which do this work are known as digestive organs. They consist of a food tube and several bodies called glands. =The Food Tube.= The food canal is about thirty feet long. Its first part, the mouth, opens back of the tongue into the throat, named the pharynx. This leads into a tube, the gullet, passing down through the back part of the chest into the stomach below the diaphragm.
As to the pancreas it is wanting here, as in the fish with salivary glands; but in its place in many insects other tubes, acting also as glands, pour saliva into the pharynx; i. e., the cavity at the back of the throat. As you see, therefore, everything is found complete in this tube of a few inches long; and you can also distinguish there a small and a large intestine.
"What symptoms did you observe?" asked Kennedy, quickly, seeking confirmation of his own first impressions. "His mouth seemed dry and I should say he suffered from a quick prostration. There seemed to be a complete loss of power to swallow or speak. The pupils were dilated as though from paralysis of the eyes. Both pharynx and larynx were affected. There was respiration paralysis.
The solid parts are sharply resonant; they are, par excellence, the resonators in voice-production; while a pliable part, like the pharynx, although resonant in a less degree, is valuable in adjusting structural shape to every condition that arises; and the most movable parts of all, the tongue and the lips, probably wholly devoid of resonance, have their great rôles to play in effecting what may be called wholesale changes in the size and shape of the mouth-cavity, which could not be brought about by any other agencies less mobile.
