As the caravan, according to its usual march of single file, moved along the serpentine footpath in peristaltic motion, firing muskets and singing "the return," the Unyanyembe villagers, men, women, and children, came running out and flocking on it, piercing the air with loud shrill noises, accompanied with the lullabooing of these fairs which, once heard, can never be mistaken.
I have thought an ounce or two of crude mercury in less violent diseases of this kind has been of use, by contributing to restore its natural motion to some part of the intestinal canal, either by its weight or stimulus; and that hence the whole tube recovered its usual associations of progressive peristaltic motion.
As soon as the food enters the stomach, the muscles are excited by the nerves, and the peristaltic motion commences. This is a powerful and constant exercise of the muscles of the stomach, which continues until the process of digestion is complete.
But if by a greater stimulus the motions of the stomach are inverted still more violently or more permanently, the duodenum has its peristaltic motions inverted at the same time by their association with those of the stomach; and the bile and pancreatic juice, which it contains, are by the inverted motions brought up into the stomach, and discharged along with its contents; while a greater quantity of bile and pancreatic juice is poured into this intestine; as the glands, that secrete them, are by their association with the motions of the intestine excited into stronger action than usual.
The simpler laws into which the complex law is here resolved, are the second of the two foregoing principles combined with a third, namely that the peristaltic contraction acts easily upon substances in a state of solution.
If a tendency to constipation exists, it can almost always be overcome by increasing the amount of fruit and vegetables eaten, also by eating cracked wheat, oatmeal, corn and graham bread; all of which increase the peristaltic action of the intestines. The small amount of water taken by girls and women is another fertile source of constipation. School Life.
All aperients quicken for a time what is termed the peristaltic action of the bowels; that is to say, their constant movement in a direction from the stomach to the lower bowel, which, as well as a contraction on themselves, is constantly going on in every living animal, and continues even for some time after death.
There is one caution as to the mode of eating which seems peculiarly needful to Americans. It is indispensable to good digestion, that food be well chewed and taken slowly. It needs to be thoroughly chewed and mixed with saliva, in order to prepare it for the action of the gastric juice, which, by the peristaltic motion, will be thus brought into contact with every one of the minute portions.
The intention of Nature, as manifested in the healthy state, obviously is to withdraw from our notice all the vital motions such as the circulation of the blood, the expansion and contraction of the lungs, the peristaltic action of the stomach, etc. and opium, it seems, is able in this as in other instances to counteract her purposes. By the advice of the surgeon I tried bitters.
Hence it appears, that the act of nausea or vomiting expends less sensorial power than the usual peristaltic motions of the stomach in the digestion of our aliment; and that hence there is a greater quantity of sensorial power becomes accumulated in the fibres of the stomach, and more of it in consequence to spare for the action of those parts of the system, which are thus associated with the stomach, as of the whole absorbent series of vessels, and which are at the same time excited by their usual stimuli.
