By its irritation of the nerves, the secretory and excretory processes of the system are stimulated into abnormal action, and an extra quantity of fluid is poured into the colon to dissolve the accumulated mass; which is about as scientific a proceeding as pouring a quart of water into a washbowl on the upper floor of a dwelling to clear away an obstruction in the main drain of the building.
From the ingurgitation of spirituous liquors into the stomach and duodenum, the termination of the common bile-duct in that bowel becomes stimulated into unnatural action, and a greater quantity of bile is produced from all the secretory vessels of the liver, by the association of their motions with those of their excretory ducts; as has been explained in Section XXIV. and XXV. but as all parts of the body, that have been affected with stronger stimuli for any length of time, become less susceptible of motion, from their natural weaker stimuli, it follows, that the motions of the secretory vessels, and in consequence the secretion of bile, is less than is natural during the intervals of sobriety. 2.
The mucous membrane of the mouth, stomach and the first part of the bowels should not be compelled to act as an organ of excretion, for the normal function is secretory and absorptive. However, when so much food is eaten that the skin, lungs, kidneys and lower bowel can not throw off all the waste and excess, the mucous membrane in the upper part of the alimentary tract must assist.
According to the first theory, the blood pressure prescribed the measure for the urine secretion; according to the second theory, the urine got secreted from the secretory epithelial cells of the kidneys, and the quantity of the matter secreted was dependent on the rate of movement of the circulation of the blood.
#Anatomy.# A nerve-trunk is made up of a variable number of bundles of nerve fibres surrounded and supported by a framework of connective tissue. The nerve fibres are chiefly of the medullated type, and they run without interruption from a nerve cell or neuron in the brain or spinal medulla to their peripheral terminations in muscle, skin, and secretory glands.
Next to the muscles as heat generators come the various secretory glands, especially the liver, which appears never to rest in this respect. The brain also must be a source of heat, since its temperature is higher than that of the arterial blood with which it is supplied.
However, we need not depend upon non-mammalian evidence for either the secretory explanation or the dual basis. An ideal case would be to observe the effects of circulating the blood of one sex in a developing embryo of the other. This blood-transfusion occurs in nature in the "Free-Martin" cattle.
The greater percentage of fat as compared with muscle in women , if it is generally true, is what we should expect from a lower metabolism and a tendency to store materials. Even those which do not primarily concern the internal secretory system would be expected to work somewhat differently in the presence of unlike blood streams.
I have also given half a pint of good olive or almond oil as an emetic during the painful fit, and repeated it in half an hour, if the first did not operate, with frequent good effect. Another disease of the liver, which I have several times observed, consists in the inability or paralysis of the secretory vessels.
Usually there is a bright glittering sheen in them which contrasts with the dead look in the irides of sexual excess or profuse uterine discharges." The activity of the glandular secretions, and especially those of the skin, during detumescence, would lead us to expect that such secretory activity is an index to an aptitude for detumescence.
