Works
Claude Bernard's aim, as he stated in his own words, was to establish the use of the scientific method in medicine. He dismissed many previous misconceptions, took nothing for granted, and relied on experimentation. Unlike most of his contemporaries, he insisted that all living creatures were bound by the same laws as inanimate matter.
Claude Bernard's first important work was on the functions of the pancreas gland, the juice of which he proved to be of great significance in the process of digestion; this achievement won him the prize for experimental physiology from the French Academy of Sciences. A second investigation - perhaps his most famous - was on the glycogenic function of the liver; in the course of this he was led to the conclusion, which throws light on the causation of diabetes mellitus, that the liver, in addition to secreting bile, is the seat of an internal secretion, by which it prepares sugar at the expense of the elements of the blood passing through it. A third research resulted in the discovery of the vaso-motor system. While engaged, about 1851, in examining the effects produced in the temperature of various parts of the body by section of the nerve or nerves belonging to them, he noticed that division of the cervical sympathetic gave rise to more active circulation and more forcible pulsation of the arteries in certain parts of the head, and a few months afterwards he observed that electrical excitation of the upper portion of the divided nerve had the contrary effect. In this way he established the existence of vaso-motor nerves, both vaso-dilator and vaso-constrictor.

Famous quotes containing the word works:
“That man’s best works should be such bungling imitations of Nature’s infinite perfection, matters not much; but that he should make himself an imitation, this is the fact which Nature moans over, and deprecates beseechingly. Be spontaneous, be truthful, be free, and thus be individuals! is the song she sings through warbling birds, and whispering pines, and roaring waves, and screeching winds.”
—Lydia M. Child (1802–1880)
“Audible prayer can never do the works of spiritual understanding, which regenerates; but silent prayer, watchfulness, and devout obedience enable us to follow Jesus’ example. Long prayers, superstition, and creeds clip the strong pinions of love, and clothe religion in human forms. Whatever materializes worship hinders man’s spiritual growth and keeps him from demonstrating his power over error.”
—Mary Baker Eddy (1821–1910)
“They that go down to the sea in ships, that do business in great waters, these see the works of the Lord and his wonders in the deep.”
—Bible: Hebrew Psalms, 107:23-4.
